mrbean,
If you absolutely need something removed from a previous post then you can possibly get the Moderator to edit it. Go to the thread and click on Options>>Report to a Moderator. I am attaching a jpg on how to do this. I'm not promising they will remove it or edit it but they do have the power and if your case is strong enough they just might listen.
As Song said in his post- 30 minutes after you post you can edit your own message by going to Options>>Edit Message. It will only show up if you are allowed to edit the message.
Regards,
