That wasn't a duplicate........it had a

Although I thank you for doing that crap joke cos I was about to !
What seems to happen on vbulletin stuff is....you click once and nothing happens, so you click again and away it goes. When you are posting you click once and it registers......and puts your post up.......but you need to click again.......the database registers this as you posting the exact same post twice and obviosuly doesn't allow it. Hence double post warning......nothing up really. Just seems to be a thing with vbulletin where you have to click twice for some reason, not sure why
