Regarding your email. Posting an email address in a forum is a sure way to get tons and tons and tons of spam at the email address - and to have it hacked. All email addresses are hackable, but those posted publicly are considered fair game. Best practice for internet security includes never posting one's email address publicly.
(There are bots and spiders and all sorts of automated scripts, constantly crawling the internet. Some have legitimate uses, such as search engine spiders. We like those. Some are trying to register fake members and post spam. We don't like them, and actively block them. Some are snatching up every email address they can find. We can't even see them, much less block them!)
(For example, we average approx 25,000 visits per day. But only approx 400 of those are human. All the rest are various automated bots which have many, many different purposes. Some purposes are respectable, such as search engine spiders, but most are not.)
If you need to share an email address with someone, you can use the forum's Private Message feature. That way, only the person you address the message to will see it. And the bots can't get to it there.
You can change your email address. Click the Profile tab near the top, then Modify Profile > Account Settings, and Email is about halfway down. And be sure to click the Change Profile button at the bottom of the page, to make it take effect. Then go back to your profile, to confirm that it's correct.
