Well, IMO if we allowed these userbars we would have to allow any bbCode in the sigs, and there is no way we could restrict the sigs to have the user bars only. User bars use the IMG tag, and if we decide to use the user bars, IMG tags won't be able to be restricted to just those userbars (any picture will work). I don't think that user bars are too terribly messy. IMO though it could cause a mess from abuse of the open signature rules to accomodate these user bars.
