I have been working on a directory website for a little while now.  It is still very much a work in progress, but wanted to get some input on it:

http://www.oolah.net/

The home page is still pretty plain, but some of the deeper pages, like the "Architecture" page (http://www.oolah.net/dir/Architecture) are starting to come together a little better.  Over time, I'm hoping to add more features to all of the pages and get them all looking good.

Let me know what you think, what can be improved, and if you run into any issues, just let me know.

A problem for submitting a site, seems your input forms say twice the same (website title) where one should be the url to submit.

Otherwise I like the clean look also.

Nice - simple - easy to navigate.  Check the wording on second line of title - I think you are missing a word 'find'.  Keep up the good work!

Like some of the other posters I like the "clean" look. The colors used makes the information stand out but the pages are not overly packed with a huge amount of information.

That is really nice...
 

Thats a really nice clean design, sometimes i think classifieds sites should be a lot more basic and cleaner on the home page

really nice work...
