Take it as a compliment:You folks are doing it right!
Posting early gives people time to set their work schedule days off.
What/Where and date in the subject line gets attention.
All the details posted,....food/drinks/raffle.......instead of "call for details"..... plus a mapquest address to make it easy to find!
Open to all makes for better participation........
You folks are doing it right!
Other people could use your example.....-Bob
