OK Ive noticed that when you make a post then change something on your profile the old post still has the old stuff. Can you change that please?

It takes a little time for the forum to refresh -usually until there is a new post in the thread in which you have your old post in.
That's a feature of the forum software, it's not something we could change on individual basis.

This type of question belongs in PTs - next time please send me or my colleague a private message if you have similar technical questions to ask.

Thanks.
