I've used all sorts of forum software, from Simple Machines to phpBB, and never found much problem adapting to each.

I post more here than on the other Heuer fora, because it's where I first found a Heuer home on the net. Some quality discussions occur on the others too, and I post in those that interest or intrigue me - less so on Vetroplastica nowadays, only when I think I can contribute something the regulars will find worthwhile translating into Italian! No problems with cross-pollination either - I've referred to IVHOC posts here before and vice versa, the same with Vetroplastica. Best that way, coexisting as intersecting circles on a Venn diagram than separate entities.

I quite like the subforums too - I can witter on about cars and racers unconnected to Heuer there without feeling I'm foisting an off-topic post on people who aren't interested! Doesn't mean you'll get away from them here though, I also have few qualms about (reading or writing) OT posts here too.

I've been posting some replies on Cal 11 too, before I started guesting as a writer there. Some interesting and different perspectives there, often without the vintage background.

It goes to show the strength of the Heuer community today that it can support so many groups within the larger community, and that's a good thing as far as I'm concerned.
I don't think Arno linking us over there is essentially different than posting re my similarly themed article on Cal 11; people will hopefully read and contribute as they see fit.
