I had a message to let me know that my box was almost full...I dispatched a PM to a fellow member, then thought to go into my PM boxes and erase the unnecessary - only to find, when my PM had been successfully posted, that both the in and outbox had automatically been emptied, and all Pms deleted.
ouch!
There was something there I had wanted to keep. I suppose it's all too late now. Is this an inbuilt feature?
I had no idea it would activate, otherwise I would have 'tidied up' sooner.....
