Hi- how many letters please Dave?

Hi- you may find these guidelines useful from Crosswords section- in particular it's best to start including details of letter count and known pattern.

We'll always try to help even without them but it does help for those of us without the paper

You can also add any missing info (such as letter count) or add a thank you to Baldric etc just by replying to your own question

I know you're right Baldric- our posts crossed but I was just pointing out to Dave that after 80 posts without details of letter counts, and some without clues, he may want to look through the guidelines and this may help him get answers more quickly
