Thank you for your feedback @curlfamilyvlog!
As it happens, we have not set any amount, I just said 25% as an example, I do believe people should give what they feel is right but if certain people think it's right to give nothing or very little, then those people are not on the same page as the rest of us.
It's a tough one to call but with the response to this post so far, it seems most of us are on a level playing field.
We'll see how it plays out!
Bless.
