hi m looking for feature where user can register, log in to website and upload a doument. user can view the history of uploaded docs also. at the other end admin can do the same also upload and assign the docs to users. admin can view n download too.
the site must use php as a script and XML as a database. that means this xml (or these xmls) can be written at runtime and must be multithreaded so that simultaneous users can register and upload the document without gettin any error.
