Couple thoughts I just had:
1) I was just perusing the topic, and you realized your missing at least 2 major projects & hallmarks of Wc3 Modding...
Heart of Storms and
The Great Troll War Mod (headed by
Dmitry Rommel and
TerranUp16, respectively). HoS is 'technically' still in development (*cough* after nearly a half-decade or more?... *cough*), but see #2 below. GTW, on the other hand, is long dead, and had tons of interesting resources & such...
I should know.
Anyway, if you wanna format that and insert it into your Compendium, I fully approve. Just make sure to throw my name somewhere; many hours of work & a lot of contacting to get all that stuff.

Hope people here can enjoy it.
2) The title of the topic is "projects of old", yet you have some 'current/finished' (Retera's) and 'still in progress' (Dawn of Chaos) stuff. If that's the case:
2a) Heart of Storms (HoS) is still in production, but it's really,
really awexome. I happen to have a lot of documentation (forum archives in Word documents, picture archives, any available models (<- which is almost none; Rommel is infamously tight-gripped and wants things fresh for the mod)), if you'd be interested.
2b) Can
I put
my modding stuff up on this topic? I mean, the more people know, the better. And, (haha), my project is so slow as to
be dead.

I totally am & plan on continuing it, but for the purposes of your thread, it won't change much anytime in the immediate future.

Let me know.
