Hi,
I've recently release a suite of free SEO and domain information tools.
I'd like to get some feedback about the usefulness and usability of the current tools and thought this forum would be the best place to ask.

NetDnx.com - Free Webmaster Power Tools

The current features include:
Whois lookup
Additional owned domains
Website traffic
Site Popularity
SE rankings
Competitor analysis
Websites on your webserver
Class C neighbors
Link validator
Sitemap creator
Google sitemap creator
Search Engine simulator
Keyword analysis
Keyword suggestions
Site keyword suggestions
Link Partner suggestions

I have several more tools which will be added in the future and hope to release keyword search popularity very soon.

What I would really like is any feedback or ideas about additional tools that you SEO experts would like included.

Any feedback good or bad would be appreciated.

Cheers
Brad
