The @ in the email address and the . in the domain name will cause \w+ to
not match. You could either go looser with
.+
or better
[^/]+
or you could be explicit with
[a-zA-Z0-9_@.]+ ( . inside brackets doesn't need to be
backslashed)
though that last won't be affected by local, so you could perhaps do
(?:\w|[@.])+
While you might have a limited set of email addresses, note that . can
occur in the username part, as can +, and we often see - in either part.
Probably best to try r'^acceptfriend/([^/]+)/$' next, then decide if you
need to be more restrictive.
