@chl I got posting rights alright, thanks!. But, do you know whether mathjax works in the blog? And if yes, how it is activated? for the moment it appears it doesn't, at least for me...

@chl To get this thing going, I have made the tables into images, uploaded them and published the post. But it would be good to know about mathjax in the blog...

@AlecosPapadopoulos I thought it was working, but I'll need to check. No time for that this evening (I'm living in France). Let's get in touch tomorrow!
