Perhaps the easiest way (for you) to suggest a new page is by contacting us.
But if you want to give more details or actually do some work (along with lots of learning), you could instead use GitHub and make a Pull Request.
It’s not even that complicated:
- learn a little of github markdown (if you want to actually format your contribution), or;
- go here and name the file
index.md(after login or create an account if you need to)
Even going there and writing your suggestion in plain text is already simple-ish enough and much better than trying any other contact form.
Somewhere in the future, we will replace this process with something even simpler for contribution.
Thanks for your willingness to help! :)
