If it is a page you edited I (or any admin) can see the edits in your deleted contributions.  If it was your own (prior username) subpage, I can restore it and move it to your present user account.  If it was someone else's I can restore it as well for use as evidence.  Do you have a rough idea of the page name?  If it relates to your prior user name you can email me if you prefer. Thatcher
