Hi,
I did try to reply last night (my time) and found on hitting the repost/update button that I got the Post it note "We'll be back" maintenance screen.
Basically for me the HTML screen allows me to use several preconstructed items in the post.
Most Posts get the "sig (Pic Date and Time, Log Message in green and Mac Specs).
These are created then held as "Snippets" in TextExpander which is an Add-on that works across all apps.
It comes with several pre made items including one that is converted in to the Date and Time.
The Sig one looks like this in plain text.

The first bit is an image tag with the location of the Pic. (in this case here at Apple rather than running me around the "Add Pic" script)
The <br> is a line space.
The date and time is held in the snippet as "%1I:%M %p %A; %B %e, %Y" followed by another line break.
Then the "span" bit for the coloured text in different font which is sized to match the board's usual font size.
The <p></p> will also give you a line break as the <p> is for paragraph.
The colour changes to grey/gray with the spec info spaced with <br> tags to have each items on one line.
The  is the unicode number for the Apple Icon which makes it show on many more Browsers as not all readers will be using a font in their Browser that has the icon at ALT+Shift+k
If I post a link to me Web site and as it has a Donation Button I have to post a notice here

Some of the constructs I have were for the previous Jive version the boards used to use.
The current one relies heavily on javascript that preforms the "little jobs" like getting pics posted, Inserting quote areas, changing to the HTML editor and back or even the Advanced Editor where you can also access colours and more Fonts.
In some cases they enclosed image tags but you can't load pics from external sites any more.
