As a premium member you can change some of the settings from "Your Account" page.
This stops your profile being found in search engines, and you can look at profiles without leaving a trace.
But as you say don't post phone numbers/email addresses in the forums, as they will still be there even if you delete your account.
Guys seem to be in the habit of posting numbers in their status bar, which is also a bit random and is not advised.
Anything personal should be saved for private messages... after all you wouldn't put your address and phone number on a public toilet wall
