The "Article Instructions Guidelines" seems to be lacking the correct items list codes which were in the Writing Articles article. These are the correct ones I got from the article:
[split][col][itemlist][b]Title Here[/b]
Material 1
Material 2
[/itemlist][/col][/split]
For pictures, you have to have them already on your computer, then, at the bottom of where you type the article, click on "Browse", find your picture, double click it, give it a name in the name field (ex: If you decide to upload a picture for the title name it Title Picture or something of the sort), then simply click "Upload Image".
It should appear on the left side under "Images Avalaible", with the name that you gave it just above it. From there, copy its link, and put it in between the codes [AImg] and [/AImg]
Do a preview of the article and if you followed these steps, your picture should appear fine!
There are also three different types of headings:
The biggest is [h1][/h1]
Followed by [h2][/h2] (most commonly used in articles... it's the one in a box used to name steps)
And the smallest [h3][/h3]... this is basically as if you were just typing in bold...
Okay, well took quite some time to write this reply, and so I hope it helps!
Don't hesitate to ask if you still have questions
