I would get the technical problems on the niche sites straightened out! Sometimes I have no problems posting as the author, but sometimes it comes back that I've posted as a commenter, not the author. Sometimes it says "my comment is being posted but must be approved by the author" when I am the author, then it doesn't show up at all. When I think that maybe I'm not signed in and try to sign in, it tells me that I'm signed in already. The only remedy I've found is to sign out and reboot the program or the whole computer. Does the fact that I'm using a Mac have anything to do with its being squirrelly?
