Nice very simple forum that stands alone or integrates with WP

Vanilla http://getvanilla.com/ is so nice and streamlined (of course I have to go and ruin it all by adding a bunch of extensions and stuff

)

So I have installed vanilla on http://scratchbuild101.com/forum/categories.php and added the extensions:

Account pictures 1.2
Attachments 2.1
Html Formatter 2.4
and Inline Images 1.3

plus a theme that sort of goes with the wp theme we picked for the main site.
