</div>That'd be useful. It'd be even better if you could make a quick RDO wiki<br>

PS: If you're a Markdown user, you can convert Markdown -> WikiMedia<br>
(RDO uses WikiMedia for wiki) trivially like this:<br>

$ pandoc -f markdown -t Mediawiki <a href="http://foo.md" target="_blank">foo.md</a> -o foo.wiki<br>
