E-mail for SP

Just FYI:

I had an e-mail where my SP mail would come, not talking abut the SP mail. I don't have that e-mail or lose the info on it anyhow, the alerts I used to get I don't get any more. Like when I'd have SP mail or something new on team page or wall. I feel I'm probably missing a lot. Sorry if I haven't written back or posted to something I should have.

If I find the e-mail, I'm afraid if I change I won't get my personnel e-mail account back. I should, just leery, not savvy.
