Seriously to be honest, good luck on quitting. Believe me sure I did quit runescape and havent played in over 6 months. I told myself "I will never play it ever again finally and I am done with it." Now I am on a private server once again. lol
Anyways if you really can quit I envy you man and respect you for trying.
Good luck where ever you are going.
Btw Sythe is mainly a community site now and I believe even if Runescape wasn't around this place would still be a great hangout.
