No one sees the slack PM, so it came off as you being pissy.
The question is can people submit designs to JTK to run a group buy without CtrlAlt involvement or do all GBs have to be CtrlAlt buys? You appear to have answered that, though that is the first time I have ever seen it stated that it will be available to others and the question about CtrlAlt involvement is still unanswered. I've only seen them treated as a CtrlAlt exclusive.
People aren't ****ting on JTK, they're just saying they're not up to snuff yet and that there are legend issues, but that they are improving. That's called constructive criticism and it needs to be heard in order to improve. If JTK wants to be a serious alternative, those issues need to be heard and corrected instead of minimizing the issues and passing them off as people ****ting on the manufacturer. The fact that you stated "when they're ready" implies that you know that they're not quite up to snuff yet.
In the mean time, people are saying that GMK has better quality, JTK feels better than SP, and JTK is priced better than GMK but JTK has worse quality on the legends than GMK and SP, so it's probably better off going with those until JTK legend issues are resolved, unless the legend issues don't bother you.
