So for every x years you've played, on the anniversary of you starting you can be welcomed, as in when the server rolls over it greets everyone online with "User Lambrago has been here for x years. Happy BoL day!" (something similar)
Then you can get some reward for time spent here, such as x credits, x*1000 mith, x*100000 gold or something similar? So the more years your anniversary is, the more rewards you get. Just a small thought I had that would be nice to reward those who look out for younger players, and makes it so that you can look forward to your anniversary, etc, etc.
