One star reviews because you have no patience suck Rated 5 out of 5 stars
I don't often review addons but lightning is probably one of the best and my most used addon for Thunderbird.
If you are reviewing and rating Lightning for use with Thunderbird 3 you are reviewing a product that doesn't exist yet. Please stop posting the one-star reviews. This review page is for the *latest release* of Lightning that works for Thunderbird 2 builds.
Please don't review this excellent work one star and demotivate the excellent developers who give their time freely to this project.
(TB 3 has only *just* come out. Software releases don't always coincide... especially in the open source world which depend on donations and freely-given man-power resources. If you follow the release notes and version numbering (as you should) you will see that Lightning 0.9 is only compatible up to TB 2. DO NOT install TB 3 if you want to use Lightning until Lightning release for this version is ready (or try the test release of Lightning given by other reviewers below -- if you do this, back up your calendars regularly and be prepared for possible problems). Please have the patience to wait for the next release of Lightning before submitting reviews for that version.)
P.S. If you donated to the Lightning project, instead of just complaining, it might be ready earlier.
