Hi Bob
A bit late to this but big congrats on your forthcoming wedding!
The best UK forum is Hitched - I have been a member there since 2001 and couldn't have done my wedding without it. I have also made some true friends there - six people at my wedding were only there because we met on Hitched in the planning stages, and we're all still friends now.
Www.hitched.co.uk and follow links for forums.
Also the site is really useful in itself.
HTH
