I don't think that is a requirement for posting an adoption request. Although, if you aren't autoconfirmed, it is impossible you you to have been editing long enough to be approved. Regardless, Canis should be autoconfirmed by now as they registered mid-November.
I don't see why you can't edit. You can edit, because you are a registered user. We had made it clear above that only registered users can create adoption request (which you are, otherwise, you don't have a username but an IP).
