Hi Steve. It's just another Forum really with about 100 members to date many post on this site also. We're trying to get an Owners Club off the ground with regional meets (in pubs mainly, funny that) so that members can get together and have a pint and a chat, compare exhausts etc. and generally get to know each other face to face. It seems to be taking off OK.
We have our first weekend national get together next weekend at Long Newton in the North East of England, should be a laugh.
Anyway you should be able to sign up no problem. Try again as I think there were a few glitches eary on. Any trouble give me a shout.
Not sure you'll have seen the PP pipe in Oz as there have only been a few fitted so far in the UK. It replaces the cat.
