Hi all, I think I've spotted a small bug in URLencode: + is not listed as a reserved character (and hence not percent encoded) even though it is listed as a reserved character in rfc3986 (http://tools.ietf.org/html/rfc3986#section-2.2). The documentation for URLencode cites rfc1738, which rfc3986 makes obsolete. Hadley -- Assistant Professor / Dobelman Family Junior Chair Department of Statistics / Rice University http://had.co.nz/
