Can you guess the number of posts required?

I think you should be able to hit your first pay out of $10 if you have no referrals with 1000 posts or there about-if you hav activ referrals, it could b far less

yes, my assumption is that if you make a thousand quality post you are likely to get your $10. So if you want it in 10 days, you have to make about a hundred a day... :)

The earnings on mylot aren't on how many posts a member makes, but on the quality of the post. Like say a mylotter posting 50 quality posts would make more $$ than anyone who posts 100 one liners. I reached my first $10 quite quickly because I had many active referrals that time. Now I don't have even a single active referral but I'll be reaching $10 on this 10th I guess. But I don't know how many posts I have done for this $10.

For earning one dollar, you are required to make atleast 50 posts. So I think, atleast your should post '500' quality posts, then you can expect 10 dollors.
