A shame that TWW doesnlt have such a space (hint, hint).
I will have a think about this.
My initial concerns are, that to the best of my knowledge, the membership system either allows uploading of all types or non, so people could upload excel sheets but also images.
The problem there is that excel sheets sat on the server could seriously pose a security threat, and that if everyone started to upload images the server would start to fill up quickly.
In the meantime, you could upload files to a file sharing site and link to there?
