I have had many problems with opening pure data webpages, recently i couldn't open the Expr Manual http://yadegari.org/expr/expr.html
do anybody here have another link to a copy or a similar page to the Expr Manual? i'd very much like to read it.

@4ZZ4 The Internet Wayback Machine is the answer to such problems, they have a spare copy of most of the internet including archives so you can see old versions of websites
