Very simple, If every body put ads here and I allow it. The first page would be full of ads. No real discussion would be see. There are already a place for selling stuff, you should put your ads there. 置顶贴 still there , you could add it there too. I put it on top just for that. I understand you get more exposure if you have your own thread. Sorry, screen is just that big. Your post is very nice. I like it. But at first post you put $5 something. If I allow it, next time somebody put like 50 dollars ghost buster. What should I do.
