Free extensions for Joomla!

Hello Guys!

I have the AlphaContent extension for xmap, but it's not working with last version of AlphaContent. Site map have wrong urls to the articles, but for sections and category all right. Articles urls have not the infromation from alias section of article, but include the section and category number.

I use this SEO Joomla settings:

Search Engine Friendly URLs Yes
Use Apache mod_rewrite No
Add suffix to URLs Yes

May be somebody have a chance to improve this extension? I think many people needs this. If somebody do it, I wish to donate some money for this deal...
