I didn't vote either way in the end but IMO the real problem with a Multi forum is that it overlaps a bunch of existing forums. Take your F7F Tigercat, if I'm looking for information about one of those do I look in Multis or Scale or Giant Scale or perhaps Warbirds ?
It may be just me but I think having too many forums which are not well differentiated makes the place less accessible not more.
Now if we were talking about Control Line that's different. Nothing like anything else round here at all
Though a few of the existing C/L forums aren't too well supported either.
