I'm not a mod or an events organiser but I have turned up to all the East Anglia Social events. I always wear my BM K.I.S.S Rally T-shirt with my name on so that any newbies arriving can easily recognise the group.
I have even been to an event where a friend wore pink fluffy ears with BM on them
(and we all know who that was) so that people would know us.
I would like to think I have made everyone feel welcome and to show them that not everyone bites but helped them to join in.
My advice would be to make yourself known, either by adding yourself to the event, PMing someone else that is going or contacting the organiser of the event to make them aware to watch out for you. We must also be aware that the events team and mods are going to be busy making sure the event runs smoothly and safely.
Don't forget, if nobody knows you're going don't expect someone to greet you...add yourself to the event!!...standard members can add themselves
