Thanks for your reply. Mir is very good, I have heard the name of 
mir long ago.
I am a frequent forum novice.
Many people in the forum have good ideas. And the information is 
good. But many of them are underused.
I suggest that the D community should make full use of the good 
information in the forum.
There should be a summary of some of the discussions. Then put a 
separate page.
In this way, when it comes to related topics later, there is no 
need to repeat them
In my opinion, D community should be organized. Only the 
organized community can be powerful. Now, D, I feel that the 
community is too loose. It's like a random walker. There's no 
clear direction.
