didn't realise you had asked this question a couple of years ago, see :

Still gives me the opportunity to post my 500th post. A breakdown of Aftermathman's 500 posts shows:

175 - sports related drivel and laughing at Americans who think New England playing New York in the Super Bowl represents international competition and provides world champions.
200 - general moaning and feeling sorry for myself.
100 - some actual PD content (not altogether useful).
25 - Some actual PD content (useful).
1 - Complaining about my maths.

Still,eat my dust all you "less than 500'ers" and take care,

Neil.
