Glad to inform you guys, that I have finally became a master. Now, I don't know what to do next, maybe I could come up with a new blog "Mashups for aspiring IMs" ? Lol.

Do anyone of you have any other interesting ideas for me or the community ?

Sorry for late reply, but it's good you asked this. Actually, when you're fixing the message $$$m_i$$$, then you have to choose rest $$$k_i - 1$$$ messages out of $$$t - 1$$$ messages (note that total messages would also decrease by 1). So, the numerator in your formula was wrong.

Thanks for bringing me to peace with this question. Guess newbie things.. I mess up with indexing stuff

Thanks great mashups for beg
