Recently I sumbitted to serveal different search engines. However, so far only google crawled me and unforuntely at that time I didnt have my meta tags up so it only got my URL and not keywords, description. Yahoo and all the others I am still not listed. How can I force or maybe get a quicker spider from Google so it can get the tags this time. Is there anyway? (I have heard adding content helps and I have been doing this alot).

Well they constantly crawl the net, you most likely just need to sit and wait =/ SEO is not easy.

Actually Google doesn't use Keywords, MetaTags, Etc. ;)

Just worry about getting quality backlinks and increasing your Google PR.

The links are the problem. I have only two or three people linking to my site which I really want to increase.

Buy text links and offer link exchanges with people.

Does posting website links on forums (like this :P) help with google and other search engines ?

I'm pretty sure it does help with your PR. WHT is crawled on a regular basis by Google.
