We've just finished the groundwork on a COMPLETE recode of the site. This recode gives us a lot more flexibility with the systems we have in place, and allows some pretty neat options.
Some features coming in the future:
File Archive - Will allow us to share files (screensavers for example).
Recommended Reading - Will allow us to share what books we like.
Video Bin - Will allow us to share videos from YouTube, Google, Yahoo on the site.
Best of all, every user can submit content that they feel would make a great fit; you don't have to be staff to help contribute!
For now however we're just focusing on the newly recoded Articles and Terminology systems as well as some lingering code cleanup.
