Installed script, and I saw index files being created, also downloaded by Google. Found google webmaster page and signed and looked at my stats. website was last crawled 7 days ago. I also manually uploaded my site index file, which was downloaded by google few minutes

(I also added .htaccess pages for all my directories)
my forums/directories are created like this
www.mysite.com/portal/forums/
So I have 1 .htaccess file under each of the folder roots
www.mysite.com and
www.mysite.com/portal and
www.mysite.com/portal/forums and each .htaccess file has its own redirect, so it will work under each folder.
When will Google actually crawl my new pages? or did I do something wrong?
In my understanding when index file is being downloaded it does not mean pages have been crawled...correct?
So what is the appx time google will crawl pages after being installed this mod? (And does this mod require google webmaster account)
