As this is a free service, emails go to the bottom of the pile, and lapse after X days if I don't have time to deal with them as the forum is for questions.
Your account was deactived years ago, hence the reason you can't login. Posts remain the property of Win2Win Limited as per the T&C you agreed to.
If you supply links to those posts you want removed I'll decide if it influences the way the forum works or not. Individual posts are not really a problem, but threads are.
