I am on a tight deadline for redesigning my website to be totally run off of databases such as sitepoints website. I am wondering if there is a free script out there that has these abilities:
Polls, Articles, Links, News (separate pages for each and the latest 5 news stories will show up on index page), ability to add authors, administration section.
I have looked at some things such as Back-End but that is overkill for what I am looking for.
You probably don't want to hear this, but there is no "turnkey" solution for a database driven website.
Each script would have to be HIGHLY customized for your site inparticular...if you have the finanical means, but not much time, you probably ought to higher a PHP/SQL programmer. If you have plenty of time, and would rather not shell out huge amounts of cash, then I recommend picking up a copy of "Professional PHP Programming" from http://www.wrox.com and reading Kevin's PHP/SQL article series thoroughly...in time you should be able to achieve many of the same things that SP has with their system.
