Writing and article would be such a great idea !
I'm sure a lot of SP members would feel concerned about this topic.
To write an article you don't need any HTML knowledge.
All you have to do is :
1. click on "Create Page" (top of the window)
2. select "Article" on the following page
3. click "Contine" on the same page
4. All you have to do then, is to fill in the boxes with your comments and information
If you want to attach a picture in your article, you just have to :
5. click "Find Image" near the "Primary Image ID" box
6. In the small box that will open, select "My Image's Only" before clicking "Search"
7. Select the picture you want
I hope it will be helpful
