Boy, I get busy offline for the day, and everybody else gets busy online.
I like the idea of rolling Q content into the CEP hak structure, but I'm one of those builders that wouldn't use a CEP version that wasn't backwards compatible to 2.4.
I've done way too much building on my PW module using 2.4 (since I've been using that since it came out in 2011, and previous versions back to 2.1) to go through every on- and off-palette resource, and every area for painted down objects, to account for altered creature/placeable/door/etc. 2da entries.
I mentioned this in a PM this morning, but I'll put it here again...one concern I have is content creators that did not want some of their content that is used by Project Q included in the CEP. It may have been mainly about personality conflicts with Barry_1066, but I wouldn't want to assume that just having someone else taking the helm would imply permission to use their works under the CEP flag without explicitly getting permissions, even if the rest of the Q content is rolled in.
