Always disclose your affiliate relationship. Most visitors will probably understand that graphic ad will lead to your getting paid, but if you write a review or use an in-text link as a recommendation, you want your readers to know that may lead to compensation as well. This ensures you retain transparency and trust with your readers, but also, it's required by the FTC's endorsement rules.
I would also like to see a forum built into the platform. Wealthy Affiliate has a unique way of building a community and I understand why they shy away from a standard forum type of format. Instead, they want to promote live chat sessions, blog posts, private messaging, and public questions where people can comment below. This type of setup is pretty cool at times, but I also do enjoy forums where I can just browse by topic.
