In Chinese, we often say somebody is our "old friend" or "old colleage" or "old classmate". If we talk in Engflish, we should be careful with these concepts.
The safest way to express similar ideas is to say "old timer". For instance, we may say "Bingle" is an old timer at rolia's forum. If your former classmates come to see you, you may have an old timers's party.
When I buy my house, I sent an email to my former classmates: "My house is a tiny one, but it can seat all the old timers".
I some sense, I can be counted as an old timer at this forum.
