Imelda, I can't think who she is but I probably know her by sight.
Geffin, we cater for many standards from super fast to begginer. With 4 groups, begginers, not too fast, getting faster and fast. The sessions usualy last for and hour or so but we're not running continualy for that hourand you can drop out when ever you feel like it, and people often do. In fact it's very rare for us to finnish a session with as many as we started with.
Give it a go. If you go down ask for Trevor or Steve and say that you've "spoken" to Phil. tell them what you hope to achieve from the club and they'll set you on the right path.
Best of luck.
