So I'm starting right now or tomorrow? .Tell me so I can start posting and is there a maximum allowed post? I checked and it only says that "Write 10 Quality Posts Each Week," so only 2 or we can do more ? as long as each week we get our quota?. Thank you so much for the opportunity to be able to join in this campaign I know this campaign will be successful

.
I may be wrong but I think there is a maximum of 10 posts per week based on some information in the spreadsheet. For example: there is a user with the comment "458 - 72 ?? only 10 accepted" in the "accepted posts" column. Which means he is only getting paid for the 10 posts.
There is no maximum amount of posts that you can do in this campaign. However, you will only get paid for 10 posts. If you don't get 10 accepted posts, you won't get any payment. So it is better to do about 15 or even 20 posts to make sure that you get at least 10 accepted posts.
