Mancunian, I am sorry you had a bad experience at the munches you attended, but can I ask that you do take into consideration all the work the organsiers do put into arranging these events and perhaps some wont have time to read this thread as they are up to their eyes making name badges, liaising with DJ's and talking to the venue to make sure everything goes ok on the night.
I would also add that the majority of munch organisers do offer 'hand-holders' to anyone who is new or who is nervous about attending, they give out contact details, arrange to meet new members outside the venue and generally spend their night running round making sure that all guests are comfortable and enjoying themselves.
Also there should NEVER be a boundary between seasoned and new members and the organiser should ensure that this never happens. If it does, and they dont do anything bout it, then I would question why they are organising munches/socials?
handy hint.....find Cherrytree and she will drag u round to everyone in the room weather she knows them or not and introduce you....and herself too!!!
guaranteed your feet wont touch the floor all night!!
