These don't seem to get checked a lot, and when they do, it seems like nobody knows anything about Gregtech to verify my application. As such it's been sitting for over two days, being told by multiple staff members to just wait because they know nothing about GTNH.
I'd propose instead of the vague "double ores" (which shouldn't be vague or take long to verify but whatever) a number of options that take equivalent time/dedication as ore doubling does on other packs be used to verify member applications on GTNH. For reference, I hopped on ATM3 and completed an approved membership ore doubling setup in around 45 minutes.
If this sounds good, I'm sure many of the GTNH players could think of several things that take that approximate hour of dedication to create.
