Questions about the forum

While I have been on the forum for a little while, I don't know much about it. Here are some questions I have about it.

1. Who are the mods? I know only of Huw and drdavewatford. 

2. Is linking a set from Brickset as simple as putting the pound symbol before the set number?

3. What is the point(no pun intended) of the points on your profile? All I know is that 1 like = 1 point. 

4. And lastly, can someone please explain the new rule on pictures and memes to me. It's quite confusing. 

Thanks all,

G
