chacha, you'll enjoy Google Analytics, as well as StatCounter. I recommend it, as it shows you things StatCounter won't, such as "bounce" rates.
Sitemeter.com is also a good counter, having some good traffic analysis. But the only drawback is it allows only one URL per account, while Sitemeter allows many projects but limited t0 100 logs.
using the free version and thing it’s enough for now. I’m also waiting for my invitation to use Google analytics but think it will take some time before I get it.
