OK. let's try this ....
Below are three possible dates (and times) for the meetup.
Tue 18th. 4 pm
Sat 22nd. 2.30 pm
Tue 25th. 4 pm
Would everyone who is definitely interested in attending please reply with one of the following answers for each suggested date:
1. I can definitely make it.
2. Not sure. Or, I can make it at a pinch, but would prefer one of the others.
3. I definitely cannot make it.
I will then collate the answers. The winning date will be the one with most definites (option 1). If there is a tie, I will use option 2 as a tie-breaker.
I know that it will be impossible to find a date that will suit everyone, but we've got to come up with something.
If you agree with this idea, please reply. If you don't ..... well, I won't make any more suggestions (until next year).
