Many thanks dear people.
Unfortunately, the next day came with some technical difficulties on the server hosting the site which disabled the database system. Then I went to a conference to a distant city and return only several days later. Then the internet connection was cut off for a few days, and I couldn't try to fix the errors until now. Really sorry for this.
Anyway, I'd just want to point out how special a solar return is. I was reminded by a friend to perform a meditation on that very moment, but it was almost 2 AM and I was exhausted after a long day of partying with friends and relatives who flooded my place in order to get some free food and drinks
(joke)
But I somehow managed to stay awake and I got some really ideas at that moment.
So, everybody, thanks for the messages ! great to have the forum working again.
