Thanks for the info ncaditya.
I have a another question for you guys. This is regarding google and alexa crawls. Lisa i know you may have an answer to this.
I submitted my site to joeant.com about 10 days. But the site hasn't been crawled by google or alexa for inbound links. Does it usually take that long? My site appear in 5th level of the directory and is the only site in that category.
Directory: Computers ~ Programming ~ Languages ~ PHP

I am waiting patiently for google to crawl my link
And once the crawl is done by google, how will it measure my site? Will i see a change in PR?
