Not sure if this is what you're asking, but if you look to the right while in the new Rezound home forum, you'll see "Start a discussion". That should let you start a new post.
To answer your question wett, there are no settings on the phone itself to make the icons & font larger on the Rezound. You may be able to search for an app in the Market to see if there is anything out there that would suit your needs.
