OT:Yahoo Messenger???

Hey all i just wanted to know whether we can post our yahoo messenger screen names so that we can contact each other? I would love to be able to talk to some of my old friends who i have lost touch with. I plan on being on here more often but i think it would be cool to be able to chat on a messenger service. If you want to contact me you can do so at yahoo mess. ID katarina49799 i would love to hear from you. hugs and luv Joyce
