Great stuff Theresa, glad you’re so psyched! I’m nowhere near you so sadly can’t help- but might be worth putting you’re looking for pals in Edinburgh in your forum title, just so locals notice it. Otherwise have a look on Facebook (if you have it), you’ll probably find there are groups on there for Edinburgh climbers as that’s pretty common.
Could also be worth asking at Alien and Eden if they have social climbing sessions one evening a week or anything similar, as that’s another great option a lot of walls do.
Good luck on the search and welcome to climbing! ^_^
