I think I have the same issue, but I just hope it is a matter of time.
Some time after I joined I received the letter with my Memership ID and so on. I used that number in order to request for registration in the Southern group forum (http://www.southern-trf.org.uk/
), but I haven't received any email as confirmation. I have tried again, but my user is still not active there.
I know they meet on the 3rd Thursday each month, in front of the Halfords in Eastleigh, but I am working up in London all the week.
I have been riding green lanes the last two weekends. The first one was ok, just a lot of pools, but the second one it was a tricky one (and I am a noob with a road bike). I was just able to do it , but I think I shouldn't ride alone. You can have an issue and then a fun day will become a very bad day...
Are you planning to ride this weekend? If so perhaps we can ride together.
