Go to Google webmaster tools (
https://www.google.com/webmasters/tools) and get verified. Basically you put a page Google generates for you on your site and they know you are there. Then get a site map made for Google to crawl and submit it to Google. I found this:
http://www.xml-sitemaps.com/
I don't know if you have a site or blog because your site isn't in your sig file...put it there. Google crawls this forum and they will find it that way.
Go to
www.stumbleupon.com and create an account. bookmark some pages you want to keep from sites you visit then bookmark a couple of your own. This create activity and you site will be found. I use a 5 to 1 ratio...for every 5 sites or pages I BM, I BM one of mine. Do this a few time then STOP. If all you do is BM your own post you'll run the risk of getting banned from the site.
Create a free blog on
www.wordpress.com or
www.blogger.com and point to your site off of a keyword. This create spider activity and the bots will find your site that way as well.
