Yes it would be good to try to create a network of groups, with the aim of giving support to each other, swapping ideas and so forth. There is, I believe a group which operates in the Telford area but I haven't been in touch with them as yet, but may do so if it seems appropriate.
I went to Saith Seren for a couple of years, but currently don't as I'm doing a formal course on a Monday, which involves travelling to Welshpool, the same day as the Grwp Clebran takes place in Wrexham. However, I'm sure I'll be going back again later in the year. As you say, it's a very active, and I must say, welcoming group.
Do you just sit and chat in your group or do you try to throw in any activities? I hope to try to get my lot to get positively involved in whatever we do as I can't envisage being able to come up with ideas for things to do ad infinitum, but any suggestions you can make would be welcome to add to those things I already have thought of to do.
