I am raja, I want to create a best email ID in gmail engine. So give me the options?

First its not a good idea to piggyback your question on someone else's. This can lead to confusion. You should start a new thread. So I've moved your question to its own thread.

Second, as noted in the thread you posted in, an e-mail name is very personal. Also "best" is a relative term. Therefore its really impossible for use to make suggestions that would be good for you.
