Great. I'm GMT (based very near Bristol, England too) and am looking for the right game to join with the right kind of people. I've DMd in the past and still run occasional one or two-shots (5e, Cthulhu, Paranoia, some fun Fate stuff), but am really looking to play in an ongoing 5e game right now (my local tabletop game unfortunately came to a premature end due to DM real-life demands).
Thanks for starting this post. I'm really interested in getting a group (possibly monthly ish) together and it does look like something might be coming together here.
dmkevin ... if you are seriously considering running a game of Tomb of Annihiliation then lets have a chat.
