i follow hamzei on twitter, same scenario. . . its something about surf's setup, as I see him available at some hours, and not at other hours. . .
could be the availability of his work servers, as my work servers block twitter, as my company gets between 2 and 3 MILLION spam emails a week
also, twitter blocked my account, so i forwarded it to my cell phone, and they replied to the message with the original email, and that went longer than the cell text message, and so i didn't get an answer. . .
idiots
