As you may have already noticed, I made a few changes on the site.
Before anything else and to keep it clean from the beginning, be sure to read the "terms and rules" of the site (there's a link down there). So, whats new?
• The look obviously, made by me in 2 days and the design skills of a sea snail. You either like it or hate it - I really don't care. If you like it however, you can still buy me a beer...
• You can now register an account on the site. Thats the only way to use a nickname on the chatbox or comment boxes. Otherwise, you will appear as "Guest". Ofcourse thats not the only reason you should consider registering. In the near future I am going to add a message board for better communication and few challenging additions, so it's up to you.
• The old shoutbox is now transformed into chatbox. Use it wisely, and don't type BBCode in it, or you may get automatically banned.

I think that's all that's interesting to mention here.

Now have a nice time at nullsecurity.org
