It's annoying, I WANT to split a few posts over two posts (ie put the download above the skew of detailed text). Wouldn't an obtrusive message like "YOU ARE DOUBLE POSTING, ARE YOU REALLY SURE YOU WANT AND NEED TO DO THIS" be better?
By default, edits in vB bump threads, so double posting isn't needed for that. The only good reason I've heard for it is for organizational purposes, but is it really that hard to just hit enter a few times for a gap?
This is anoying. I have like 10screenshot to post on my forum and I have to wait like 2min between each post because the posts will be merged and I will lost all my attachment.
