Been looking at the Merlin Clubs section of the website and noticed that the club just up the river from me "severn sailing club" is on there problem is the website link for them is not the correct one. Please see below.
http://www.severnsailing.org.uk/

Ps how do i get Tewkesbury sailing club added to the list ?

Cheers Russ, I've changed the link.
I'll email you about Tewkesbury.
