Plans yes, but currently some limited possibilities. DotNetNuke5 and the upcoming DotNetNuke6 are coming with a set of complete new control (Telrik), including the WYSIWIG editor for the forum.
Only problem is, that all updates of the Swyx Forum DNN always fail and I wasn't able to figure the reason, nor to solve it.
For the moment I plan to setup a complete fresh DNN and try to merge the content, but that's quite a lot of work and I haven't found time for doing it.
As with DNN6 they are going to change a lot again which frightens me in terms of updates I have decided to wait for the release of DNN6 first and then perform that manual update.
