Just for the record, Colin knows the score about trade membership.
I warned him that he would probably be "encouraged" by other members to sign up, but I agreed that as the RIB market is a new venture for him I had no problem with him testing the waters here first. After all, I started this thread because it looked like it might be something interesting.
If people like his kit enough to buy it, then I'm sure he'll do the decent thing. On the other hand if he gets nothing out of posting here, there's nothing lost either way.
