Hi Lisa! Welcome to UKY!!
You've definitely come to the right place...there are lots of us in and around London. I for one have had a lot of trouble making friends, too. I've been here three years now, and have finally, finally started to feel like I am making some headway...so it takes time!
Tell us more about yourself! Are you working? Do you have children? Are you planning on being in the UK or London for awhile? What do you like to do in your free time? We wanna know *everything*.
Keep an eye on the events board here at UKY. We often have meetups that are put up there. But aside from those, lots of us meet up for coffee/lunch/whinging/shopping/etc at regular intervals so if you're up for getting together sometime, let us know!
It's great to have you here and hope to see more of you soon!
