E.g. for lfgss you could use lfgss@mydomain.co.uk BBC you'd use bbc@mydomain.co.uk and so on.
That's really annoying for other people if you're on mailing lists or Usenet, for what it's worth; the default behaviour for the web archives and for many mail/news clients is to show LFGSS or BBC as your name, unless you make sure your real name is appended. Problem 1: if LFGSS or BBC is the subject of the discussion forum, it looks as if you're claiming expertise or authority for something you don't own. Problem 2: you won't be the only person doing it. And since almost all the people doing this are unclueful, you can find yourself tarred with their stupidity (as well as drawing some heat for what is, in those contexts, a really annoying practice).
