So, it's so easy! Great! It seems I've to get used to this clicking
more. It seems I've become too cautious with this, when I've really
- really, waited after each click there. (I mean a few months ago,
and my connection was the same; sometimes, one such click took one
whole break for coffee.)

I seems, there are simply two kinds of people wrt. calendar/time. I'm
usually happy if I can figure by myself which day of week is today, but
I wouldn't even try with something like 4 days ago. But I understand
I'm not the brightest here...

So, maybe, some day, with: linux-kernel-for-dummies.org such things
could be reconsidered...

It looks, after Kay's notice, my main problem is solved. And your current
explanations are also very precious to me. Probably some things considered
here could be done a bit better in the future, but I guess there is enough
urgent work with git or kernel too, so let's say it's OK for now!

Thanks every good git people!
