Hi lucabrazzi
What bernie and jazzgirl are alluding to is that it is a good idea to give the clue, the letter count and any you have placed. The name of the crossword is also useful, and whether it is a cryptic one.
When you click on "New thread" you will see these tips:
POSTING TIPS
1. State the name (and number if available) of the puzzle in the thread title. "Stuck", "Help!!!" or "Last One" aren't very useful titles.
2. Give the clue number, the clue and the number of letters and please put this number in parentheses at the end of the clue. If no number of letters is given in the puzzle, then tell us. It also helps to know if the clue is cryptic or general knowledge.
3. Tell us which letters you already have. Try to use spaces around the character you choose for missing letters as it makes it much easier to read. Also try to ensure that the letters given match the stated number of letters in the clue.
