Your full email address is not shown anywhere on the forum...giving
you the privacy you need.
BUT...it is a much better idea to have purpose built email accounts
for your different web activity. I have 5 different ones to do with my
website and 4 others that I use for various levels of interaction. I
keep one email address (my ISP provided one) to only be used for
'official' personal business. I am very careful and keep records of
which email address has been used for which purpose.
Hope this helps.
