Hi, I would like to suggest that CTR forums be createdd alongside with this wiki as there are things I want to discuss (such as making a video comparing this game to Spider Jack) and I also noticed that you hate ads and can fix that as well.
Forums are a good idea, but they'll require a bunch of people to develop them and look after them. If I were you, I'd first poll the participants of this wikia whether they will participate in a forum.
Go to Special:CreateBlogPage and write a blog post about the forum feature you propose. Tell you are requesting for comments. Other users will see a new blog post on the main page and will likely comment on the idea. Also see help on creating polls if you want an actual poll in your blog post.
