I suspect that theres still a small detail that OP left out (not sure if I am remembering twitches IRC incorrectly though). The channel on twitch IRC has a # prepended to it. So you may need to change:
Code:
%s GET $+(/twitch2.php?id=,$urlencode($1),&follows=,$urlencode($2))
To:
Code:
%s GET $+(/twitch2.php?id=,$urlencode($1),&follows=,$urlencode($right($2,$calc($len($2) - 1))))
