For some reason, links in posts are in the wrong color. Should be link and not link (http://www.somesite.com). Internal links have the right (#post_) color.
It's only an issue on this site, not in the latest SVN.
Seems, it's because some links in posts gets the classes "bbc_link new_win" and others gets the class "bbc_link".
Internal/external link color difference maybe? And yes, it's also an issue in SVN's.
