We have been using rich editors to let people format blog comments.  All of the mobile browsers display them correctly but none of them interact with them correctly.  New code has been added to allow mobile browsers to post basic comments while allowing full-computer-users to use the full comment features.

The jHTMLArea editor from http://jhtmlarea.codeplex.com/ has added to Mercury.  Why would we need this when we already have a full featured rich editor?  Because sometimes you don't want people to have all that power.  This is a good editor for letting people make comments on blogs and on forums.  They don't get full HTML access and they don't get to upload files.
