I'm not sure what benefits there are with being a legendary
There might be no such benefits, but ranking to Legendary with Merit System will Somehow represent that you have been rewarded 
Sir Jet, I would like to be the person to give you your 1000th merit if ever that you already have 999. I will be keeping an eye to your Merit points starting now. Please don't ask me why.
Well thanks for the offer. Please make sure it's a decent post, and not one where I'm having a strop.
I'm a bit tetchy this morning, as they have turned the power off in the supermarket cafe I'm in at the moment. That means I'm on battery power for the netbook, and I can't run my node,or do some of the website updating I had planned. I could I suppose, but the screen is a bit small, so it is easier to work on the notebook.
I'm not sure why Joel isn't a Legendary, it looks as if he should have been promoted. What happened to TMAN, wasn't he a hero a month or two ago, and he should be Legendary now?
