Relating this comment back to the point about some users finding too
much contrast difficult, does any one have any statistics about the
numbers of users who fall into these groups - and also what other aids
they might be using. (I know a friend's child had difficulty reading,
it wasn't dyslexia, nor irlen lens sydrome; they weren't quite sure
exactly what. Whatever the problem, and it doesn't really matter,
tinted glasses helped him - he used them for everything; PC, books
etc. )

The thing I'd say here, is that anything that's not a link shouldn't
be underlined. Given that people do have differing needs when it comes
to contrast; and, as others have pointed out, it's not the contrast
between foreground & background that is important for links, it's the
contrast between different words.

Yes.

As someone with no disability, I'd agree with that. The sites that use
hover & put a coloured background under the word - make it very easy
to see what's a link.

Do you mean having essentially an image based page, with images of
different signs (does ASL have a different grammar to spoken English,
in the way that BSL does) - which would, in fact be the equivalent of
producing the page in French or any other foreign language. Or, would
you envisage having videos of someone signing the information?
I guess the ideal would be to have both text based and at least one
other. Would I be right in also assuming that, like many deaf British
Adults who have grown up with BSL as their first langage, native ASL
users tend to have reading (of English) levels below the average
anyway? ANd, I guess, some will come from homes where neither ASL nor
English is the first langauge of the rest of the household. A
multilingual audience!
