Ahhh, got you old son.
well why was i here when the 400th member was congratulated eh eh eh , exactly!
Don't worry dave, that number is just a key acting as an identifier in the database's table of member's information - it has no fixed connection to the real world! You were
the person who set the record for the site having 400 members on it's books for the first time, and that's good enough ol' chap

Not that i'm biased of course...
