Don't project who you wish/want/hope the other person is onto them. Let them show up to you as themselves. Then see where that takes you.
Great topic Ann.
Don't be rude, reply with a simple emoticon to anyone who takes the time to show interest in you
Don't expect a reply from "someone" if you decide to show interest in "someone"
Don't assume the other person is only talking to you. Until there is a mutual agreement to actually date each other exclusively - you're free to talk to everyone. (Some people CHOOSE to communicate with one person at a time - that's an individual choice.)
Don't let yourself become emotionally involved before meeting in real life. Communicating any other way does NOT automatically mean a romance is developing.
Developing friendships here is similar to networking. As Dawn said - you have to contact people, get out there and meet them. DO use this site as a way to meet as many people as you can. Attend events, have coffee with someone, put together an outing and post it. Hang out a bit, see if there is a mutual spark IRL. If not - as Katie stated above - don't take it personally. You can choose to embrace the friendship as it is, or move on. ( I personally know couples who developed a romance out of a friendship - it can happen.)
This is an important one.....Don't post bathroom or bedroom shots unless you crop them. We don't want to see the toilet or unmade bed behind you.
