Alternatives to supporting Ubuntu

Hello all,
For a while now I have been using the little amazon link that comes installed by default, whenever I make a purchase on Amazon. May I ask, does this even do anything for Ubuntu? I hope so. It seems like such a great way to contribute, and also an easy way to do so, especially considering those of us that already shop on amazon frequently.

Having asked/said that, is there any other ways that those of us in the Community can contribute, without having to know how to code? I am trying to get there, and I’ve been looking into helping improve some of the old tutorials and outdated Wiki/Documentation, but Bazaar was confusing.
