One other major protip to consider:

NEVER use the same e-mail addy for everything you do online, e.g., casual social communications with friends, co-workers, and fam; business/professional/job dealings; and your interactions with the online MAA/MAP communities. Always use a single specific e-mail addy for your controversial communications with fellow MAPs, and nothing else. Keep that specific e-mail addy far away from any socnet site like Facebook or Twitter that you may communicate with other people in your life on.
