So, how does a trackback work?

[Halfdeck]

I recommend for now only leaving comments on pages like

analsextips.net/a-beautiful-pleasure-pain-anal-face.html

comments on pages like

analsextips.net/some-more-free-anal-pages-and-gallerys.html

will not pass much value. The cache won't be refreshed for months either so your comment will take forever to show up.

and when approving comments, allow live links not only in nicknames but within the comment itself - that way people can embed links inside a paragraph of text.

Too many interlinking between a handful of blogs can expose the entire network. If the "club" is small its no better than crosslinking with yourself.

Lastly, how do you plan to keep track of comments? If I spam your blog with "relevant" comments and you only leave one comment on my blog, then its not a fair trade
