You appear only to have 45 links to your site in Google:-

http://www.google.co.uk/search?hl=en...ww.usalug.org/

which is a little surprising as you have over 18000 sites that contain your URL:-

http://www.google.co.uk/search?hl=en...usalug.org/%22

Google doesn't seem to want to count Messageboards as links and if you can get links from sites that have a PR of 5+ then that will help. Good luck.
