Answer 1

Here's what you say:

Hey want to catch up sometime?

Answer 2

You say, "we should catch-up sometime."

See? Simple. Very very simple.

Answer 3

a) It depends on the scenario.. if it's a girl you haven't seen in a long time but once knew pretty well you could just say "haha just thought of that time when _____(memory), seems like soo long ago and i miss it! if you're ever free, I would love to catch up with you on oldies or have a small reunion? let me know"

if it's someone who you didn't know well, maybe contact a couple of people you know a little better and say "oh a bunch of us are having an oldie reunion so if you want to come join i'd love to catch up with you"

b) in that case, it's more safe because she made the first move. write on her wall or message her (however she contacted you) and say.. "oh hey! wow i haven't seen you in forever, it seems like we didn't ever get a chance to talk to much.. if you're ever free sometime do you want to grab a cup of coffee and catch up on old and new stuff?"

if you're not interested in dating, just say just as a couple of old high school friends? if you are.. then just leave it at that.
