1) fixed by changing url format :)
2) I think i have reported a issue on that one 3) Is this w3c forcing us to switch to ATOM ?? Why is it complaining on atom stuff on a rss 2.0 feed?? this validator doesn't complain: http://www.validome.org/rss-atom/validate
EDIT: re #2, I'm not the one that reported this, but there is a issue for it..
