This extension looked promising, but the developers didn't keep the promise. Major issues for me are: permissions system not working for different users in frontend AND backend, troubles with files management. Tech support has been totally unresponsive, not even replying to repeated technical mails and eventually to my request for refund. Money lost forever? maybe, maybe not: it seems that they're aware of great discontent from their customers, and they announced they're restructuring their business. Let's wait and see...

The lack of such a functionality in TinyMCE made me look for another editor (commercial and compatible with J!1.5). No discussion, your extension will make life much easier to editors - thanks a lot for that!

I was looking for an extension that was close to DotProject in spirit, but simpler and well structured, and of course integrated to Joomla.
Project Fork matches exactly my needs, its interface is clear and intuitive, despite a few little bugs that will need to be fixed (however they do not prevent the system to work).
