What ■■■■■■ me off was that I’d taken the time to reply to all the repliers with their new questions, sent it on its way and it said “not logged in”, so I logged in and it didn’t post the reply, prompting me to type it all in again. So I thought zebidee it and didn’t bother.
When I’m bored again I’ll probably re-type it up.
Nice one Rob !!
