Check to see if you accidentally are going to the mobile version of the site on your computer. Look at the URL at the top of the browser window right after "groups.google.com/forum". If there is a "/m" after that your are on the mobile site. Just delete the /m.

Dunno for sure what is going on with your permission to post, but it sounds like you are not logged in to your google account on your computer. At the upper right of the screen when viewing RAS check to make sure you are logged in to your Google account, and sign in if you are not.

Of course all this applies only to the Google Groups viewer for rec.aviation.soaring. There are other viewers, as has been discussed many times before.
