I don't understand why you would close the 3.5-3.7 forums for new mods. I understand a new 3.6 mod is a very RARE occurrence but why turn off new threads (mods)? It doesn't hurt anyone to have them remain enabled- it's not like you can have less 4.x threads because 3.6 forum is open...
I
maybe can understand putting the early 3.x mod forums under some 3.x umbrella to "clean up" the look of the site but preventing new mods from being posted just doesn't make any sense.
Truthfully the same logic goes to why the 3.0 and earlier mods were ever "archived" (deleted) to begin with but what's done is done... Don't make that mistake again.
This forum itself runs 3.6!
