Well, vBulletin normally converts email addresses and web urls automatically. In this case, the user (and I) did not wrap the entry with tags, but something did because the EMAIL tags showed up bythemselves! I assume it was either photopost or vbulletin. Irregardless of that, my users who DO wrap tags with BB code are reporting that it is not working anyway.
Take a look at this post: http://www.rs25.com/classifieds/show....php?product=1
Notice after the description I have entered a line with email, URL, bold, and italic text. NONE of the text was converted. Therefore PP is not working properly.
