I recommend going through the process of:
1. Post your ideas in the New Method thread and see how multiple people feel.
2. If you really believe that the idea is good, then work to prove it. Develop the algorithms for each step.
3. Make a new thread for the method and get more feedback from the community now that you have developed it.
4. If you still believe, after having developed the method, that it has some importance, feel free to create a wiki page. If it is widely viewed by the community as great, and is popular enough, they may even make the page.
The wiki is supposed to be a place of learning and a place where established things are described. It isn't for adding just anything you want. I understand that maybe you want to make it official by putting ideas on the wiki, but that isn't enough. Ideas should be proven to be great if you want the community to notice.
Did you notice the caution message that was added to the page that appears when creating a new wiki page?
