I've been working on some more updates to the new ATK design. There are no dramatic changes, but here's the changelog anyway:

- Squashed many small style bugs
- The site no longer loads inside the shoutbox on first load
- Updated the ATK Gallery to work with our new site
- Adapted links so users can directly join our Mumble server
- Brand new shoutbox which is far superior to the old one
- Added our twitter feed to the homepage
- Now able to "Like" the ATK Community on Facebook
- Reapplied spacesaving to postbit
- Fixed and improved the spoilers tag
- Patched security hole in the Downloads Area
- Added "Total members that have visited the forum today" to forum homepage
- Added "Total guests that have visited the forum today" to forum homepage
- Increased the number of database backups to twice daily again
- Reintroduced "itrader" for reliable forum sales
- Installed registration spam protection
- Replaced all the smilies with much better ones
- Slightly tidied up the "About Us" page
- Re-added the option to change your PC specs in settings
- Added links to the ATK steam group under "Communication" module
- Optimised homepage module ordering
- i40 banners placed around the site

The original plan was to code some more complex things, but that's going to have to wait until the summer . Let me know what you think.
