I am sure that when my friend arrives he will be most impressed by the amount of thought that has gone into the replies to this request - and will post or get posted any specific requirements.

One point, as I understand it, exemplified above, is this. If I were using a braille reader, would I be aware of where the embedded links in this very thread were going to take me before I clicked on them?

If anyone finds a new user possibly called "Clever Evil" on line, be prepared to be astonished by first the depth of knowledge about "pop" and folk/country, and second by the lightning wit.
