Marc,
OK, let's give this a try. I have attachments allowed in 'Blown & Injected' only at this time. To see the 'file manager' option, it has to be a 'new post' or you must be on the 'full reply screen' and you must enter some text on the screen (you cannot just reply with an attachment without causing an error). I expect some initial problems but if this works out I may try allowing attachments to the rest of the BB, keep the files as small as possible. I may have to prune some older topics that are just chatter if server space starts getting too full.
