Discussion of mapmaking works!

... so, what's the status? Should I hurry, or will it still not be ready by the end of September?

There's no need to rush, although it will depend on other mapmakers. If we get 7 maps, we can put them in the campaign, but I don't think that will happen before mid-September.
Regarding secondary heroes - we can create them, but they won't be included in the last map.
