Who is a new user I am adding more letters?

Not a new user but nice avatar!

I'm guessing you're lacking some much needed punctuation in this question.

Maybe you meant to ask, "Who is a new user? I would like to add more letters." Although this makes as little sense as your sentence.

I am not a new user, and I think, in English, 26 is pretty much the limit.

I hope that answers your question...whatever it was.

ya lost me woman...
