hello:
i want it to be clear that when i test i test for many different types
of disabilities and just one example ware this techneck would not work
is if you had ten links with the same name you have now made it harder
for both a speech in and a speech out user. any time you would like to see
me use a screen reader i am always open to it as its in portent to stay
engaged with the user and i consider my self the user Lucy
