We have a limit of 4 images/post but there seems to be no limit to the number of videos that can be posted, people are posting a lot of videos, the pages take ages to load and the browser often hangs/crashes with so many flash video players...thanks
Confirmed as an issue by vBulletin, so hopefully will be addressed soon: http://www.vbulletin.com/forum/project.php?issueid=37804
Since we are talking about videos, I'd like to add that if someone quotes a person who posted video, then it should appear as a link in the quote rather than embedded. I saw this feature on some other forum.
