Hi Dave,

Yeah, "visited links" struck me as being perhaps overly specific as 
well. But after I considered other things we might want to track as 
"visited" it seems justified. Wouldn't it be weird if the buttons an 
email application remembered they had been used and were continuously 
highlighted?

Anyway if you think of some other things let me know.

Cheers,
Jan
