Traveller's Aid Society
Nice one, horus, and what better title for it?
I think the primary benefit of a 'guild' like this would be to learn which Rpol members are interested in playing the genre, and having a forum where we can discuss, advertize and respond to game proposals without pussyfooting around all the site regulations that tell us we can't mention this, and we can't discuss that.
Obviously, as a General rated forum we would still have to use our fruits and pastries, but that's no hardship.
Otherwise, ideas for house rules, interesting weapons, equipment, people, places - a supplement to each supplement, if you like. Ideally, material that is suitable for all versions and all settings.
I'd love to help you out with it, but time is always a problem for me. If there was a little job that didn't require regular attendance, maybe.
