Re: k2 for bbpress
Find the .post rule and add overflow: auto; to it. That way there will be a scroll bar at the bottom if anything is too long. overflow: hidden; will simply hide it instead.
Also, if you didn’t know bb does let you search.
Hit up http://www.nyquistcapital.com/forums/search.php . You can also add a search form to your template but I’m not sure just how.
