Well done and good luck!
A few golden rules.
1. Most important ( because if you don't do it, it annoys other people - the others only prevent you from getting the best out of the site) Put ALL your questions relating to a particular crossword or quiz into ONE post.
2. Give full name of crossword / quiz
3. Let us know how many letters there are, and which ones you already have.
4. Let us know the theme - if there is one.
5. Give any other information that would make it easier for us to help you.
Meanwhile, welcome to the site. You're not 'green' so no-one realised you are new.
