Hi,
Registration issues are usually due to one of three reasons:
1. You're on the Stop Forum Spam database. Hopefully not.
2. There's something else odd about your details, e.g. it looks like an off-topic commercial account (viagra@freemeds.com, that sort of thing) or the username is rude.
3. You're using a non-functional e-mail address or (rarely) the activation e-mail doesn't arrive.
If you PM me on here with a username and a valid e-mail address, I can do a manual registration,
Roger
