This is the second design of the Webnauts Net.

Therefore, I would appreciate any comments, suggestions or even hard critiques to improve for the following issues:

* Markup and Semantics (coding);
* Operating Systems & Browsers Compatibility (including PDAs, cellular phones, screen readers, etc);
* Navigation;
* Accessibility;
* Usability;
* Visibility;
* Discover ability;
* Credibility.
