Suite of Perl Scripts

Hi,
I'm looking for a suite of perl scripts (or individual scripts that can be intergrated) that can do the following -

- Mysql relational Database front end (web based add/modify/delete/etc.)
- User management and payment processing
- Mailing manager (email/newsletter to users)
- Private messages between users
- Forum

I would like them to be intergrated so there is only one login and users can move freely between each script.

Any ideas?
Thank you.

well If you are looking for them to be integrated your best bet (at least for the last 4 items) would be a groupware system.

There are plenty of them out there for free. Just go to hotscripts.com and search for groupware.

You could tell me your opinion on those you tested as well as I am searching for a good one as well but as I will change my host in the next time I haven't yet decided.
