You are doubted about whether the Organization allows your website idea to be listed on the site right ? The better way to get the answer is, contact the Organization directly and send a summary of your website idea.
Also, if the website idea is similar to the funded websites, you can go ahead & post your request. Even though you posted, I understand that, there are some verification procedures and you can check with the support team at that time.
Hope this helps you to start moving. Wish you all the success in the name of Jesus Christ.
