Here are a few suggestions:
1. Ask a question in Gen Chat. Even if you know the answer, ask anyway. There is normally someone that will answer and strike up a conversation. Talking alot in gen chat gets you recognized, even if you talk to yourself, lol.
2. Use humor. Make fun of yourself and lol alot.
3. On your profile at the top is Calendar. This shows the events that are happenning for the day. Show up at the events and say, "Hey didn't I see you at _____"
4. Read profiles and find people who have listed something you know about...besides sex, lol. Strike up a convo with people who have similar interests.
5. This is not for everyone, but join a House or Family. When you join a House or Family, you gain instant friends. Make sure you look into the house deeply before you join so you know what you are getting into.
6. Pick one club to hang out in. People tend to frequent the same places, so exposing yourself to the same group of people will get you recognized.
I admit, I don't have an answer for everything. I do however have an opinion on everything. Just ask me.
