It once took me a few weeks before my website appeared on google, if not you should try sending the message again. They may not have gotten your application. I have a feeling that wont help, I registered a freewebs one on google and if you look at some searches, they are subdomains, your best bet would be to keep trying and waiting. How long have you been waiting?

ok, I don't have much time to go over the other people's suggestion. Here, All I can understand is that you are trying to get your site on google. Here are the things you should check before you begin to.

1 > Is your site neatly designed.? Does it show out the theme of your site ? Is it easily navigable

THIS is something which you must keep in mind.. always ( http://www.google.com/webmasters/guidelines.html ) byheart it..

2> Now, that you have made your site good n perfect, Go to DMOZ.org and find an appropriate category and submit your site. This is the reason I suggested your site to be neat and clean in point No.1. Since, real humans who hardly have any time to care for you... will check your site

3> Go to www.google.com/addurl.html and submit your site there.

4> If you have a fairly large site, Go to www.google.com/webmasters/sitemap and use the feature called sitemap which allows google to index your complete site.

5> Hunt for friends and pals on the net who have their websites already indexed in google and tell them to put a link to your site.

6> PAGERANK is a very important thing you have to consider. If you put your link on a site with pagerank 9, your site would be indexed within 2-3 days. but thats not possible.. LOL. So now you have to check that the pages who link to you have atleast a PR of 2. To check page rank go to http://www.checkpagerank.com
Pagerank is a crappy technology from google which helps the rich to grow more rich and poor to rot in hell. Ahem.. Well, in other words, unless other sites don't link you, no matter how great your site is, Google will pay no heed for it. So, you have to impress google by improving your pagerank. It is a simple no, which determines the no. of people linking your site. The nos. are in logarithmic fasion. So getting PR6 is 10000 times difficult than getting PR5. And getting PR4 is 100 times difficult than getting PR3. I hope you get my point.

Bravo for you, I hope you enjoy now getting all kinds of hits and are able to share the knowledge you appparently love so much...

Glad to be of any small help (Former US Navy similator operator, programmer and maintainer...A7E attack aircraft and S3A antisubmarine warfare).
