All ideas posted on Peak Oil Idea Exchange must be filed under an existing top-level category, and ideally also under an appropriate subcategory.
Once you've decided which top-level category your idea should be filed under, click on the category name from the Peak Oil Idea Exchange homepage. A list of all sub-categories will appear.
Please scan the available subcategories to see which one your idea should be posted in, then click the one you would like to post under. At that point, click "Suggest a new idea", which will bring up a page for idea submission.
If none of the existing subcategories seems appropriate for the idea you'd like to introduce, simply click the "Suggest a new idea" link provided after the list of subcategories to be taken to the idea submission page.
