Joomfish is one of the best extensions i use.
It is a very strong translating extension since you can almost translate everything in your website.
I even managed to translate a automatic date&time script in the footer of my website.
At first, joomfish seems a bit confusing, but with some logical thinking and testing you should manage to get it setup easily.
Howto use joomfish: First of all, design and create a website like you normally do. When finished, install joomfish, and enable it.
Joomfish translations are like a layers that lie upon your original site.
Install the core joomla languages that you want to use as translation. Set the default language (preferably your foreign language) in the extensions - languagecontrol section of your backend.
Then go into joomfish then joomfish languages, and set the primairy - secondary (and so on) languages.
Then go into the translate section. Now pay attention to the following, you have to select a language from languages - select language drop down box. Select your primaire language. Then in the other drop down menu (records/select state dunno i use the dutch language dont know in english) select which part of your website you want to edit like menu/modules/content etc. When using primairy language and setting up primaire translation, just copy all (joomfish has a copy option). Set the location of your language selection buttons. Select primairy language, publish it, and test it in frontend. If all is fine set the secondary language in the drop down menu. Set the items you want to translate in the second drop down box. Open the corresponding items and fill out the form. Publish all translations and your done.
You can translate almost everything in your website, from contents, menu's, module's, fill out forms, custom html etc.
I suggested translating and publishing the primairy language first which should be the same language your website is in. This easily let you see what is happening and how, thus making it eassier setting things up for secondary language (the actual translation).
Since some users complain it is difficult to use or its hard to setup i felt the need to explain a few things.
Take your time and read, also try things out. As i mentioned before, joomfish creates a layer over the normal website, thus you cannot destroy anything in your "normal" website configuration.
It really isn't hard to setup and i really don't understand what problems some people have seting it up. If one needs help setting it up add me on joomla forum under sebastianv.
Excellent extension!!!!
Sidenote: Do not use with sh404sef. sh404sef messes up things, which ends up in a buggy website. sh404sef creators have not come up with a solution although problems allready exist for a long period of time.

Secure live analytics does what is says, nothing more and nothing less.
It doesn't block anything!! It only informs you on attacks performed on your website.
It automaticly sends you an e-mail when an attack is performed. The information you recieve includes, ip-adres, why blocked, attacks used, total blocks (which doesn't have a function since analytics only reports), and which site was attacked. I haven't used the sms function so don't have a clue how it works.
It also reports bots crawling your site.
In combination with an ip-block extension you can easily block out unwanted bots/attackers!!
I rate it 4 out of 5 stars, it does what is says it does but the information/statistics are very basic and it doesn't offer any kind of protection (only information).

Great straightforward extension!!
Easy to install, easy to use.
When key got lost, access your website through ftp, rename this file /plugins/system/jsecure.php and one has access to the backend again. Set the parameters again, rename the file back, and enable the plugin.
Uninstall one does through extensions - install/uninstall.
Can't be more eassier!!

First of all, what does it do?
Security News: Summarizes security news headers, which are clickable. No feeds nor email subscription needed, just goto guardxt main screen.
Version check: Checks the version of Joomla, of Guardxt and installed components. Great to see a summary of which components need upgrade.
File Guard: Checks permissions, and can set permissions (only 644 and 755), also does a file comparison of what file's have changed.
Joomla Server Configuration Check: Checks how some security settings are defined. Like is default admin active, is configuration file writable etc. This sorta also gives you hints on what to change (make the red light, green ;-))
PHP Checks: Checks how the global php.ini file in configured. Has the ability to start a wizard for local php.ini
Installed like a charm, very easy to use, nice lay-out. A must have for every joomla site. It gives you an overview of the more important security settings!

One of the best modules to increase/decrease front size. No need to edit css files, this module can have px, pt, em. It doesn't alter any css nor template files. Support is one of the best i ever encountered. Nice and polite folks, always answer within a day. I had a problem with java-heavy extension which didn't displayed the images right.They released an update within a week to fix this problem! Excellent program and excellent service!
