Good question Brain!
Yes, UBMC Glan Dena and Low House trips are technically joint meets so these would count.
If you need to get your quota of trips up in order to join, as a member of the UBMC you can come on any of the MAM meets (since you are an affiliated member). The Meets calendar can be found here:
http://www.themam.co.uk/index.php/meets-calendar-mainmenu-41 although on closer inspection, it looks as though this is missing some dates (I'll find out why).
A couple of good ones coming up soon that I'd recommend are:
* Martin Lane's Low House trip on
14/15th June (Martin is and ex UBMC Gear Sec and general all round nice guy) - He usually makes a very large Chilli for everyone
* Tom Murray's
Sunshine Meet at Glan Dena in mid-September (Tom is an ex UBMC President - you may remember him getting mostly naked at Stanage 2013 and doing 'Commander Says')
Both these trips are well attended by 'young', enthusiastic, super-psyched UBMC old gits and are always a good laugh!
If anyone is interested in joining but you are unsure on anything, just let me or Ian know.
