Hi Adam,
I've noticed that a number of builders (especially those starting out on their first builds) often have trouble locating suppliers and/or services in their particular area. Maybe a listing of suppliers that have been used PBG folk might be handy thing for new builders as well as old.
I don't know whether it'd be better as a forum section or a site-page (I can see the pro's and co's of each approach), but something that covers anything from decal-printers and "bits and pieces" suppliers through to full-music suppliers and local luthiers/guitar techs (and all points in between) ... maybe something that can be looked up by either item or state/locale.
I know there's a lot of the info already within the forum's pages but it's spread out over a myriad of different topics - but centralising this info should make it a lot easier to get to.
Anyway just a thought.
