Hiya.. I had to say that we should be NO LIMIT to our friends list. After you play TT for awhile, you make some really good friends. My friend list is always full, I weed it out once in awhile but it's very tough when you meet someone you really want to make friends with and your list is full DOH!
I can look at my friends list and KNOW who every single one is, and the only DOWNSIDE to having TOO many friends, is... When I first log on at any given time, I usually have 4 to 6 friends msg me right away. Great friends, I am lucky.
Tip: If you are a lower lp toon that has just made friends w a higher lp, DON'T say, "WHERE SHOULD WE GO?" hehe .. that just happened to me yesterday .. too funny!
Keep your friend list clean, and don't just USE friends for River. I have a couple friends that I hope I don't USE for River, but I DO promise them to CFO or CJ w/ them some day! PROMISE!!

Ty Peace..
