I do agree that any signature that requires a scroll bar is excessive in size, and shouldn't have a scroll bar taking up even more space. 100% in agreement with this suggestion.
You think you got it bad. I'm still on the stock Xenforo theme (the really big avatar images put me off going back all of a sudden), no signature height limit so people's signatures like Vexd's are in full view. Anyway wasn't there a rule set on oversized signatures anyway?
This would be better manually enforced, as there's no way to view spoiler tags in signatures without the scrollbar appearing
Wait...wait... You mean to tell me that in 24 hours, I get to start enforcing the Rules on Members Accounts? Dark, you can officially skip my Birthday this year. This is the greatest gift of all!
