I have been so busy lately in studying and stuff (I study computer scince at UC Berkeley) and had no time to update and keep track of my forum,so I decided to sell it and I am now getting 3-4 emails a day.The problem is that I have no idea how much should I price it!

What would you price it if you were in my shoes?!
