Yes, I realise that, but I'm in the unfortunate position of having to deal with a set of very IT-illiterate users that are barely able to grasp the concept of an Internet forum. Making them press a button to insert the attachment tag into the post is not user friendly because they won't understand the point of doing it, and I'd have to train every new user to press the button except where they have written a description of the attachment. I can see I'm onto a loser with this request and it's because I'm using IPB in a way that it wasn't really intended to be used - as a poor man's document collaboration tool rather than a discussion forum. But it doesn't seem like there would be any harm in having a setting to not require a post text when there are attachments, and it sounds like a very simple addition. Would it help if I begged?!
