Hi all,
I came across this site, it has very nice themes for webmin and I would like to share.

Check out my screenshots here:

From the website, they will even create a custom theme for free for your own company(you have to make a request).. and I think that's really cool

Thanks for the input. The normal webmin themes get old ;)
