ppl can leave u msgs and when u sign in the bot on ur msn will tell them to u
also has msn status image (nick and personal message,right now my PM is the link so ppl will know how to msg me)

u can also do it in ur own website by HTML so if html is alloswed in this forum, u can do it in ur sig which is cool
topcs u might find somone posted an invite
