63814 Non-Profit Membership

I am the webmaster of a non-profit sports website, and we need to password protect the site. Again, when I say non-profit, I mean non-profit, meaning that I don't have much cash. However, if you would like, I'll place a link with a small icon on my site for the lowest bidder onto the site. The site will NOT be making money off of this, so please keep this in mind. Thanks. I need someone who has great knowledge of a free/low-cost (under $20) password protection script with (most importantly) the following features: 1 - Automated Membership Registration 2 - Email confirmation 3 - No multiple signups Member's Features: 1 - Account modification (i.e. change email, password, etc) 2 - Account removal/deletion 3 - Forget password feature or New Password request feature that sends member a random new password Admin Features: 1 - Easy html file that I can cut n' paste into the pages, so I can place a login form directly onto any page. 2- Members List - I need to be able to view/edit/delete/add users and view their account details (i.e. email address, username, name) 3 - Bulk email feature (the members will receive a weekly update for sports scores and results) ***Modifications to be performed: ***I need the programmer to integrate the password protection with a php bulletin board system
