Description on google

When I type my website "thebookclubsite" into google, I get this for the description of the site.

www.thebookclubsite.com TheBookClubSite.com book discussion. ... www.thebookclubsite.com. User Name, Remember Me? Password. » Site Navigation ...


It used to have a different description (before installing SEO). How do I change that? Is there a way to do that? I don't want it to say user name, remember me etc...thats kinda useless.

My second question is sometimes my google results vary...like last night i was 1-10 of about 1619...today it is 1-10 of 417. It seems to go back and forth between those two numbers. Anybody know why it might do that?

Any help is appreciated...I'm new at this stuff so I'm trying to learn.

Thanks!

I think I posted this in the wrong section...sorry!

Google fluctuates some with numbers of pages indexed, I don't think really anyone understands why..

Also, make your welcome headers into an image. Google and other search engines will index that text because it's on every. single. page. for them.. and it's up at the top.

vbSEO also recomends that you place it under your navbar/login thing as much better placement.

You also have 2 places to log in on the first page, and several instances of enticing people to register. I'd wager that since those are at the top of the page, and shown so often, they think those are fairly important keywords for that page.

how can I make my headers into images? do you have a link to a tutorial or something that can teach me how? I noticed this sites is an image but it has links as well...how do you do that?

THANKS!

P.S. I like your site...I just might have to register on that one
