The first and most important thing in getting into search engines is having a decent TITLE meta tag. The title tag is that which appears in the top left corner of your browser, and that which appears as the title of search engine results.
Get as many keywords as you can into your title tag as most search engines these days use this is the primary identifier for the site - providing that the content does match the title.
You could also try googleads but if your not selling naything it may not be worth it.
Posting it on the forums is a good idea to because it provides a link TO your site and will improve its overall position. (hint)
I have had endless battles with search engines and you may notice that you can go up and down all the time.
Dmoz is a great idea as suggested but do STAY AWAY from those companies who promise inclusion to hundreds of search engines - they dont work and they will make your site go down in rankings, perhaps not even appear at all. Just submit them to the big guns individually. IMHO it takes about a year before you have a good foundation with the search engines - this is a game of patience.
Do follow web building guidelines especially where design, layout and META tags are concerened.
Best of luck with your site
BTW whats the link ?! ?!
