[xwiki-users] Uploading the file with message in Bulletin board?

Folks i am planning to have bulletin board application on xwiki. I came across link http://extensions.xwiki.org/xwiki/bin/view/Extension/Bulletin+Board+Applicat... and i loved it. Is there a way user can also upload files while posting his message on bulletin board. Are there some other bulletin board applications also(apart from the http://extensions.xwiki.org/xwiki/bin/view/Extension/Bulletin+Board+Applicat...) for xwiki so that i can select awhich serves best for my requirements?
