When it says 10+, that just means 10+ characters. Like, say "Good job on the mod", or "Awesome mod." Something like that.
ah thanks
Don't think so. On 3dm, there seems to be two types. The points you are asking are permissions (积分). Which is based on the number of posts you make. Whenever you make a post, a gold notification will pop out with something that says +5 on it. That is another set of points (金元). Users may create a thread that either requires you to have a set number of posts, or pay a set number of points to view the thread.
Should be something like that if I understand correctly.
Well, when I went to go get the links for a mod that was requested earlier, I tried just putting a period, and I got a popup that said something in Chinese, then 10. So I typed out a comment, and it let me get the mod. Maybe that's just me.
