Hi,
When you are on the box to type a reply to a PM - the link to 'Forum' goes to...
https://www.ubbcentral.com/version7/ubbthreads.phpubbcfrmAnd on the subject of PM's - there should be a confirmation to delete entire thread - the button to delete is very close to the reply to PM - and could easily be clicked by mistake.
Right that is the last from me today (thank goodness you all cry....)
