I would like to use DBMan to create a membership script similar to those used by web portals. Example: www.excite.com. Visitors to the site can register their own user name/password and then fill out personalization questions.

Then each time a visitor to the site logs on, I will download their info into a temporary cookie so that the info can be used throughout the site.

Has anyone implemented anything like this that can give me insight before I start this project?
