Member registration and spam

Just a quick note, I've gone through and deleted a huge number of members (many more than were on the members list that hadn't finished the registration process), only members who hadn't posted anything, apart from a few who looked genuine.
I'm sure I've gone and deleted some lurkers, so I apologise, sorry!
Feel free to register again. I've made a few changes to the registration process which should make it more tough for the silly spammer automatic bots to register.
If anyone has any issues registering, feel free to email me: tom (at) worley dot co dot uk
Again sorry if I accidently zapped anyone genuine!
