Thought this may be helpful as there are a couple things I do that I haven't really noticed being mentioned. Should be common sense, but....
I will look at couples that RSVP to local parties, and especially ones we attend. This indicates that they are very likely to be actively looking for playmates and are actually willing to get off the couch and drive someplace to meet people, assuming they actually attend. I have seen people sign up and never show, so something to keep in mind.
I also like to look at "Who's On". It shows members that are at least actively online and lists them by distance (closest to furthest).
Lastly, if someone viewed us and opened up their pics and they look interesting I will check them out.
Of course reaching out will be based on whether it looks like we're a match, but sometimes you can find gold from flipping over a few rocks in the stream.
