I voted "maybe"
This was based on the idea that all posts would be open to all but ride out, supplier and specs could be country/region specific.
On the down side, it would dilute some threads, create some fractionality (is that a real word?) and duplicate a lot of similar posts. I have seen it in other forums and some are very active and others have no activity.
I am with ttask'ie. with the newbie stuff. Straight in with a question, one, two posts and gone. Especially when they claim to have been lurking for a while but never seem to have read the straplines on a lot of us regular posters. I go through stages of using the "manage ignore pref" to block me from seeing some of the few post wonders.
Nice to be asked though.
