Frankly, I do not know how I did before to write without mistakes and carefree. Easy to use, even under Linux / Ubuntu, very complete with many dictionaries, besides an absolutely perfect service, with accessible people (even if they work on the other side of the Atlantic) and involved. Of course, I am particularly pleased with the software integration efforts in the Linux tools, even if sometimes it does not work very well (such as anti-oops carafe change since the last version). But overall, it is indispensable.
