Since I can't access alphacontents author's forum at this time I decided to go ahead and write a small review and note a problem I had with it so that others with the same problem might have a chance to fix it.

First off, this software seems to be a very good alternative to the commercial mosetstree extension with an impressive set of features and a wide range of configuration options. One thing that would be nice for some of these extensions is a readme or install file with instructions on how to use it. Since I am new to Joomla and components I couldn't readily figure out how to get the directory to show on my site after I installed it. I had to scour the forums and found there that you need to link a menu item to the component. As soon as I got that figured out it was a breeze.

I had only one major problem with it so far, and that was that alphacontent was not showing my items under the category/section's. I went to there forum and saw that someone else was having the same problem. The problem turned out to be that alphacontent relies on Joomla!'s version information provided in version.php. By taking out Joomla! in that file you will break alphacontent. To fix it you need to either use the original version.php file or edit alphacontent.php and alphacontent.html.php.

To fix it:
Find all the instances of these lines in each file:

if ( $_VERSION->PRODUCT == 'Joomla!' ){
$nullDate = $database->getNullDate();
$now = _CURRENT_SERVER_TIME;
}elseif( $_VERSION->PRODUCT == 'Mambo' ){
$nullDate = "0000-00-00 00:00:00";
$now = date( 'Y-m-d H:i:s', time()+$mosConfig_offset*60*60 );
}

and add this below it

$nullDate = $database->getNullDate();
$now = _CURRENT_SERVER_TIME;


Now you might ask. Why mess with version.php anyway?

Some site owners do not want their visitors knowing what software their website is running for many reasons, including security reasons.
and It seems that Joomla! does not have the option to remove the Joomla! notice at the footer of the site on the admin panel, and It is much easier to edit the version.php instead of going thru every php file that uses it and commenting it out.
