#1 Preview -- It would be really helpful to be able to preview a posting before committing it. As is, we just have to go ahead and post it, then edit any changes while it is live. The ability to preview is definitely my #1 request.
#2 Wysiwyg composition -- few of us know much HTML, and hand-editing HTML went out of fashion a long time ago
#3 Position the completed post as current -- when done editing, the thread should be positioned so that one is looking at one's own post, for a final review of it.
We post in a small window, with no wysiwyg, or even much by way of buttons, to assist. If we want to do anything but straight text, we need to edit in raw HTML -- which most of us do not know much about. Please give us some assistance.
