On the relationships: It is possible for relationships from MMOs to work, the key is to not play a game looking for a relationship, dont forget it is real people you are talking to and thier true colours can come through, also you do need to talk through vent/TS/skype because there is always the risk people lying about thier gender, its just a fact of the internet and text chat. Also dont forget just because somone posts a pic of them doesnt always mean that is them.

And always take it slow online, talk for a bit in voice chat, then when you feel you are getting to know each other be careful about how you meet if you choose to meet up. The key is to take it slowly.
