I think we can do this as a team work. Things that we need:
1. A mysql db with one table with three columns
may be you want to add some info fields, like email or whatever
2. A php script doing:
a. connect to the database
b. process a form with u/p
c. redirect to secure zone or to login.
3. A php script doing:
a. add new users to the database.
b. other administrative task, i dont know what is needed
4. some php code to validate each secure page, redirecting to login when needed
I will propose some ways to do this if I can make the time, but a good start is actually knowing what is needed, I am not a pro, so, I cant do this with no help.
metvas, do you have the script to take the support request, send the mail, etc, etc?
