It would really handy if AC published where he was going to be. I'm not sure if it's possible. Maybe from his point of view he gets booked and the slots get filled so all is good and it relies on the group / organisation to get the word around
I don't follow any particular organisation so knowing which place has an event coming up is quite hard to do
After this weekend i will have seen AC twice and both times it has really been a stroke of luck. The first time someone let me know about a day at Mini Medics and this time ^^^ well, has just been really lucky
Maybe if AC was to list where he was going to be it would involve quite a lot of faff. He would have to include contact details and info and would no doubt get inundated with enquiries for something he's not even organising directly
If you felt like this was something you were able to do, AC
, that would be terrific but i understand it could be a lot of hassle 
Cheers
