Perfecto! Rated 5 out of 5 stars
Thunderbird 24.1.1, Lightning 2.6 running on OpenIndiana (of all platforms). Integrating nicely with Provider for Google Calendar 0.25. Thanks for the great work, sending through a donation now :)
It's a real shame that other folks are failing to RTFM and use the reviews section to moan about an add-on generously provided for free - rather than rating the actual functionality.
