Absolutley, you can.

You may check out sites on below official WA Bootcamp thread

Bootcamp Comments Affiliate Bootcamp - The Comment Share Post (Day 7)

So the niche itself would be the make money online niche. Promoting WA, you're targeting an audience who is looking for training to make money online.

I have no issues sharing my site. It's workfromyourlaptop.com

Not exactly, but I've built a site promoting affiliate marketing and online business in general and promoted Wealthy Affiliate as a solution in that niche. Possibly not what you're looking for, though.

Hi, people may not want to reveal their sites...
The easiest way to find example sites is simply type into google - "Wealthy affiliate review"
All the results you see on the first few pages are people within WA who are promoting WA and have a lot of experience under them- hope that helps and best of luck!
