CodePlex is the bleeding edge. If you download the entire Forum directory (which is what is there) and place that in a DotNetNuke 5.2 or greater install, you can use nant (if you have it setup) to build the installable (this is how i package the module). As for an official release, I am really waiting on what goes on here (making sure priority items are handled) and also need some Telerik wrappers added to the core (or I have to remove the Telerik features I integrated for here already). 

Tom,

please be aware that the editor is incorporated via the texteditor provider, i.e. you may use any editor you like (like FCKEditor being used here).

Hello Sebastian,

yes I know that. But from Chris' statement it was obvious that the Telerik provider is the reason for cutting compatibility to older dnn versions. I guess I have to figure a way to get my server updated. Unfortunately all attempts in the past ended in strange error messages and I never found time enough to fight them down till the end.

Thanks for your reply!

Tom.
