The www is what it is. Whilst I don't want to put you off posting here, I think I need to be realistic in saying once something is posted on the web, it can't be unposted.
We do our utmost to keep this forum as safe as possible, but even so, there are limits with what we can do.
Like I say, I don't want to put you off posting, but just have to be realistic about things.
However, even if someone really has the forethought to go searching the net for something you might post, what can they realistically do about it?
