I've played with both of these WYSIWYG webpage
content editors and find them both more then
adequate for my needs. Since it looks like
we've lost Iceape, and it's WYSIWYG editor,
Komposer is a replacement. Except, it appears
that Komposer has not been updated since
2010-03-11.

BlueGriffon on the other hand looks to be
very active and compiled for Windows,
Mac OS X and Linux. I've installed the
RedHat RPM BlueGriffon on Mageia 2 & 3
and it installs, and runs, just fine.
Including putting the icon in the correct
location in the Application Launcher menu.
Only problem I see is that there is not a
64-bit version of it.

Perhaps the Kompozer package manager can
make the switch easily. Or simply maintain
them both.

Thanks
