Currently the attachment upload capacity is 256kb which is Ok for most stuff I guess, however I wonder if it may be increased slightly maybe to 600kb?
The reason for this is that with a recent document I uploaded I had to split it in half. I don`t envisage myself or anyone else wanting to upload 'massive' documents but the little extra capacity would help. It would save a lot of editing photo's , text etc in word docs to send to pdf.
Of course after zipping these up it does compress them but I still found on these quite small docs they were still too large!
Not sure whether this is possible - it may be a limit of phpBB or of course it may be your restriction because of your storage space, if it is then fair enougth - its accepted.
