MythenderBe warned, this plug-in does what it says, but an undocumented "feature" is that it also appends "autokeyword" to the meta tag regardless of what is written in the post. Even a blank post with no content at all will have "autokeyword" as its keyword meta tag. Easily remedied with a tiny bit of modification to the php, but underhanded at the very least.
On functionality alone: 4 stars... considering this kind of shenanigans? 2 stars tops...
