Hi Jo,
I'm sorry to hear that you've been struggling to find us, but really glad that you're persevering.
The women meet in the nice, warm sports centre changing rooms

(porch entrance opposite the 5-a-side pitch, don't know where in the building the women's changing room is, sorry) from about 7.10-7.15, then around 7.20-7.25 drift up to the slightly less nice, colder changing room

where the men get ready (I think it says 'Visiting Team' on the door, but I could be wrong - it's just automatic for me these days) for club announcements before starting running around 7.30. Between our keep changing rooms and there being at least five minutes 'plus or minus' in each step of the process you're right, anyone would think we were hiding!
My suggestion would be to turn up around 7.15 and meet up with the women while they're still being chatty in the warmth of the sports centre changing room! That said, Alix, who set up these forums, is our current women's captain and I'm sure she'll either reply on this thread or PM you with a better plan whenever she next checks the board.
Hope this helps, and maybe see you tomorrow,
Nathan.
