It has been a while since the sign in problem began in December 2008. Fed up with YM 8.0, I upgraded to YM 9.0 Beta. Still all my sign in attempts failed. My last try could probably in the month of February this year.
Today, without any intention to chat or check my off line messages, I opened my YM. I couldn't believe I just signed in my YM!
Does this mean that I'm into YM again? Well, my answer is NO! I don't feel that YM is as hot as before. In addition I still doubt whether this will be consistent. Sorry Yahoo...
