For EE Matters:
I got this from jadedata but he put it so well, I've "borrowed" it with permission:
Please do not email me with questions that are not posted at EE. This violates the spirit of the membership agreement and is not fair to other Experts or my paying customers.
If there are already Experts participating on your question, let them know you have emailed me as a courtesy.
If you email me, include the address of the question you want me to look at.
Please do not attach databases that I did not expect or ask for specifically. If I didn't ask for it, I won't open it.
