Mozilla is:
http://en.wikipedia.org/wiki/Mozilla_Foundation
http://en.wikipedia.org/wiki/Mozilla_Corporation
http://en.wikipedia.org/wiki/Mozilla_Messaging

and they have internet sites mozilla.org and mozilla.com and they are presenting themselves as *Mozilla* the home of Firefox and Thunderbird. Mozilla Foundation created the Mozilla Corporation and Mozilla Messaging entities, that now works very slowly on Thunderbird project side. Mozilla, i.e. Mozilla Foundation, is in position to change how these two department/subsidaries/whatever work together, but currently they seemed content that very little happening on Thunderbird side. I find this poor.

Before you say something like I should not complain about free software, I would like to mention that I have actually donated money for Firefox and Thunderbird to Mozilla.

Mozilla: Please put more effort into updating Thunderbird.

It is more like two departments of the same company. Their internet sites are completely interweaved.

http://www.mozilla.com/

If that separation is the reason why Thunderbird progress at snail speed compared to Firefox, then that separation is poorly constructed and they should find a way to make Thunderbird progress.

Mozilla, thanks for Firefox 3.5x, now could you please put some focus on finishing Thunderbird 3.0? Why does this have to take forever? And perhaps even get Sunbird/Lightning ready for version 1.0.

This is getting far out, but why stop with the chemistry teacher? They should go dig out the ore of the rare metals out of the ground, that will teach them...

The point here was to learn electronics. It already takes enough time, trouble and errors for children to learn to put ready made components together and understand how they interact. It is important for the future interest that they can actually achieve to make it work.
