Firstly, I'm not sure why my username was chosen for the first example!!! I can assure you I have many friends!! :-D However, I digress.
1) Emsr2d2........ (capital letter required at the beginning of a sentence)
2) Correct.
3) This is not really a full sentence. I would say "Do you have any questions?" or "Do you have a question to ask?"
4) As previously stated, "anything" is one single word.
I do not have any other suggestions for you! I will now go away and think about why I don't have any friends. If you can think of any reason for that, please let me know!!! :roll:
