https://addons.mozilla.org/en-US/firefox/addon/bbcomposer/
A nice feature rich html / etc inline composing tool for posts. Gives you WYSIWYG (What you see is what you get) ability in posting new articles. Also note: the 1st post via posting a new article thread done on that page does not auto linkify http links. Run Firefox. Install that addin. Right click on any text entry field and pick BBComposer. Be warned, the first time I see you post something with a rainbow gradient or blink attribute I will wipe every electronic device in your family. ;-)
