Its user interface is a bit disorienting however. (after a few minutes.. it really looks like this forum would be better accessed from a Phone browser).
How about a tutorial on how to use its features?
My discovery was a "floating" blue circle (o) button with a pencil in it.
That seems to be suggesting like GMail to "compose" a new message, like an email.. which I think will be posted to the forum stream.
I don't see a [Submit] or [Post] button, but see [Close] at the Top to the Left and [Next] at the Top to the Right. Geronimo! I choose the [Next] link.
Okay that seems to work.. (next page offered a POST) button Top Right and after its posted the little (elipsis ...) midpage to the Upper Right opens a Phone like menu menu with [Edit] for editing the Post.
You need to [click-on] a Post to pull it up into a mode where the (elipsis ...) option is available. Takes a little getting use to.. think of it as a game until your comfortable.
