The tutorial is missing info about how to use the Multiple Captcha Engine plugin.
All in all, I believe this is a good extension with many choices, but it is still not perfect to receive 5 stars.
The extension looks fanky but the developer has made NO documentation on how to make this work and you have to find it out yourself. Yes, even though that he CLAIMS there is documentation, in reality there is NO documentation. I personally lost 3 hours looking everywhere. And don't consider asking the developer, he doesn't even reply to customers with PAID versions or in forums.
He (or they) works hard for making many many plugins but there is no real care for his customers. Compare a super-duper documentation such as the Akeeba Backup with this non-existent trash.
Dev, I 'm sorry for the hard critic, but someone should shout truth about Joomla's sake.
It seems good. However, it is very unprofessional compared to other extensions.
I could not configure my site map in the way I would like.
-There was a stupid green stick icon next to each link.
-The sitemap doesn't break in columns if you have a long menu.
-I cannot remove the title(name)of the menu.
-Sometimes, the order of the menus is weird. i.e. The footer menu was first (on the right) and the main menu was second (on the left).
-I have a bilingual site and it doesn't recognize other than latin.
I didn't try support. I was already dispirited from what I saw on the reviews.
Don't install except if you wish to have an unprofessional site map or you can't do otherwise.
If the developer decide to develop it further or support it better, I will definitely follow him.
