I always wondered how much do you invest in this site, does it take a lot?
I see that some sites are paying a lot of money to their member after only a couple of months of being active, and i don't think that the are in profit, especially if they are putting their own ads on the site.

I don't have one, and never had.

I have no site like that, but i plan for it maybe soon.

i do own one ptc now but may open another if someone pays me for it
