No reason to be ashamed!!! 
Every handicap is different and needs to be traded separately…! This makes it so difficult to make something really accessible for everyone…! I only know what is are the difficulties for me personally - but even I have sometimes problems to imagine what a blind or a deaf person struggles with…! However, since I founded the network Chronically Academic (https://chronicallyacademic.org), I know some people with other handicaps and I get feedback, i.e., on that website… but as I said, I am also not aware of every problem which disabled people might have…!
Great!!! That is also exactly my attitude!
For me personally, only this community platform is sometimes a bit difficult to access (as described in a previous post) - Nethserver itself is pretty great for me to access…!!
However, this is only for me and my specific handicap…
For people who have a visual impairment, the GUI should definitely be make more accessible (which is now a separated topic Server manager accessibility improvements) and there are certainly other handicaps for which one has to adapt other things…! Hence, lot of testing is required and lot of work…!
But all together, we will make Nethserver more and more accessible…! certainly not perfect for everyone but at least “accessible”!
