I've tried this on MULTIPLE sites, and it won't let me adjust anything (Yes, the license key is in). It's always 2 posts, 2 paragraphs apart, in the same order (the default). It won't link by taxonomy, tags, or published date. It won't do more than (or fewer than) 2 posts. It won't space them more than (or less than) two paragraphs apart.

PLEASE FIX.

EDIT: So you apprently have to download TWO plugins, the plugin itself, and the "activation" plugin. Once this was done, it works fine. Bumping up to 4/5 tacos. Probably worth the full five, but this process over the last few days of trying to figure this out without a clear guide (there is a broken link to the guide when you install the plugin, but it's hard to even see).
