Thanks for your reply.
I will go through my files and add some small comments, write a brief description on how to install and send it to you later tomorrow.
Maybe I forgot to tell the point with this hack. Lots of time the user links to files like their own scripts, images and so on from (usually) some free web space and these links always end up dead sooner or later. By giving them a small space, they can link locally from the server and it's generally a bit better to have files in folders than in the databas. It's of course also possible for the users to have a private page or for moderators that may need to do FAQs for their forum or what ever.
I have some more ideas for further development but would like to share it before I mess it up to much
Thanks again for your interest.
