I'm surprised that it has taken me this long to find this post. Thanks Harro and I'll start experimenting with some of this stuff. For those that are just starting out, and trying to first get their site indexed by Google, you do not need to do it through them. This generally takes longer (I think the subdomain is /addurl.html or something like that). If you get a backlink from at least a PR5 site, you should be indexed within a couple of days. After getting indexed, then work on getting your
PR increased by more (and relevant) backlinks.
