Here is, following some advices, it is true that it would be practical to be able to visualize at a glance the requests which found an answer on the site.
So in this purpose, I would ask the person who found his happiness after having made his request to edit his message and to add [RESOLVED] in front of the title of this one! I am going to do it for the requests already solved, but I expect from the future applicants to do it themselves afterwards. And I will soon set up a device that will facilitate and clarify all this! Thank you in advance!
