do you mean an actual message from the site itself (like a "board message", or do you mean a message from 1 of the administrators/moderators?

I've had it in reverse (actually it was me who started the conversation), because I wrote mentioning a post in depression wasn't their anymore, and I got a response.. oh my mistake, I shouldn't have removed it.

on a related note, what annoys me is when a thread gets moved from it's forum, but in the forum it's still their

example:

a few weeks ago, I came across a wholel oad of threads in other mental health, which wern't meant to be their

they'd been moved to the relevant forums, but you could still access them via other mental health (the only diffrence was it stated above the thread had been moved)

I'm not sure why this happens.. if a thread gets moved to it's right forum, it should be non accessible from the other section
