Having a quick scan on the British Airways Executive Club forum on Flyertalk, I notice there are some “Dos” or meet-ups in the near future. It's a good chance for newbies of the points game to learn tricks of the trade and meet equally points-obsessed individuals. I've been to a few in the past and it's always been a good laugh.
There's one in Manchester, UK – Friday 15th March 2013. 17:00-late. Details here.
And one in Jersey, Channel Islands, UK – Saturday 27th April 2013. 12:00-14:00. Details here.
Slightly off-topic, don't forget you can always use BA97.com to see if someone is flying through the same airport at the same time as you. Usually people will let you into lounges (though I've never been fortunate enough to meet someone using this method) and it's a great way to meet new folks.
