i am setting up an adverts database and want to use dbman.

i have set up the default user correctly with the view option only and it works fine.
i also want to set up users with permissions to add and delete ads (no modify). again no problem. but i want them to create their own usernames and passwords which will then be passed to the passwords file.

I dont want to have to issue passwords, but that seems to be where i am stuck at the moment. is there no way for new users to post usernames/passwords directly to the passwords file without having to go through me first.

it is essential that users be able to delete their own records, otherwise i wouldnt bother.
