As base rules need use wiki syntax in Forum. See at http://moodle.org/help.php?file=wiki.html
but use double chars:
**hello** - Bold
// - Italics
__ - Underline!!! (instead ++)
-- - Strikethrough
~~ - Subscript
^^ - Superscript
"" - Quoted
%% - Code or Monospaced
@@ - Cite
AND
`` - Disable Wiki syntax!!!
In other tools need change markup to double chars too!
doubel-char markup (maybe exept headings) is more confortable for me as well (wackowiki uses it , and I really like it 
)
maybe it would be good to let admins configure wiki-markup-brackets as they want?
