You might find some stimulating volunteer development work at
sourceforge. A module I think needs writing (though I'd be glad to learn it was already written) is one to do logging in and user validation in CGI. It would be quite a challenge to make something that was flexible enough that users could drop it straight into their scripts. As a minimum it wd need to handle logging in, registering a new user, creating encrypted passwords, emailing lost passwords, and logging out. It probably ought to be flexible about where users store info, perhaps by outputting everything via DBI.pm, leaving the user to pick the underlying db. And it wd need to handle cookies. When I've raised this before, a negative response has been "it's too specific - do it in a script, not a module". So you could become famous by proving the doubters wrong.
