Hi Matthew,
What a coincidence! We're based in Bath also.

We're long time users of OpenACS... :), and remain extremely enthusiastic about it. There are a few acs people in the area in actual fact.
Drop me a mail sometime, having OpenACS people around is always good news for us. Are you an IT professional? If so I'd like to hear a bit more about your skills and background as well.
TCB
Simon
