To keep it very simple, all you really have to do is post whatever wherever. It may be moved to a different navigation area by one of the admins, in which case you'll be mailed.

If you're feeling pretty good to have written a word document, or excel spreadsheet, that's fine; use Add to Folder > File.

Add to Folder > Page allows you to write a new web page. Any images or files you want to attach to it go into the same folder though, so we like to use new folders to group related items together.

1. Add to folder > folder (named my new thing)
   
2. In the folder, make new files for your scripts and utilities, and a new page.
3. In the page, describe what your thing does, and link to the files from step 2.
4. When you're editing your page, you can upload images on the fly. Please make them .jpg or .png format, .bmp is very slow.
5. After you're happy with the results, go to the folder view again and select "Use content item" from the display menu. Pick your main page, and you're done.
