in my opinion, i think it's best if you place a banner at the top page since it gives a better look for your site, and also, you might want to change your logo, it's kinda dull... the body content is ok though, the links are properly arranged. the welcome message is aligned center, change it into align left.. you just only need some little revisions well it's just my opinion anyway. your site is ok.
you site built with "Website Value Calculator"? if so there's nothing special about such turnkey website because it's very difficult to compete with others.
well, i just check your sites. Sorry to inform you that your sites can't show the stats of sub-domain sites
you should add private services, not everyone want to publish what they check... Maybe somone want to check something worth..
