Thread pages are corrupted?

Off subject. Having issues trying to post. I create the new message, then the options are Create topic (which I’ve done), “Cancel”, “Saved”, and “Preview”…where is the “Post” button for this feeble minded senior ? I would search in “help” but it seems it’s not working. Also can’t find help on how to post. Sorry for bothering you but it’s the only way I can think of, no searches work, etc. Thanks Maybe you can enlighten me.
