I've recently signed up as an affiliate, and today noticed on my new topic that there was an option to click with this "I wish to earn thread boost affiliate funds from this thread". I was just wondering how that works? I haven't found any information about what it is, and whether it would be a good thing to have it ticked on my thread or not.

If you select that option (and hit the "Save" button next to it), you will become the "thread boost affiliate" for that thread. If someone boosts that thread while you are the thread boost affiliate, you will earn an affiliate commission. Right now the thread boost affiliate commission is 50%.

Maybe you can create a thread about the awesome product X. Become the affiliate of that thread, and ask the people who sells X to boost your thread. If you manage to convince them to boost the thread, half of the coin is yours!

That makes sense now, thank you : )
