As far as the Neo Version is concerned I tried it a few times but I can never figure out how to actually get image codes unlike the older cardmaker, until that is fixed and until it replaces the old cardmaker what could be done is lots of promotion through other social media (Twitter, Facebook, Reddit, etc.). That's all I can say for now
You don't get image codes from the new one; basically, you have to save it to your desktop first, then reupload it on Imgur or whatever.
But then again, YCMaker doesn't care about updating so...you get the point; we're stuck with the current one as-is for internal saving and the Neo New one with everything else (including its own issues).
As a not so active member and a bit of the outsides of the forum, I think I might actually have a bit of a unique insight into this.
I think there are multiple issues that are intertwined with each other that drive away newer members. And some of these are literally unfixable. (namely 1 and 3)
1. Lack of interaction with newer members
Alright, I totally understand this one, and I am admitadly part of the problem. But you just have to look through Casual- and Advanced card design to see the huge ammount of actual quality posts that go without any feedback. This is a HUGE turn-off for most newer posters as they are on the forum for interaction in the first place. Though I do try my best to comment on topics with 0 comments.
2. Lack of a drive towards big projects like AGM
If 1 wasn't a problem then this wouldn't be a problem either, but with the unfixability of problem 1 a nice alternative would be to drive everyone into the Clubs & Organizations forum to make cards together, as people will be forced to give attention to other people's work. Maybe this would ruin that part of the forum though. Also, I just realised that I have never made a club myself, so can I really whine about this? A good alternative to this would also be to have a specific sub-forum to make card making projects that are too big for one person and have it be in the "Card Maker" part of the site.
3. Difficult to get into "the circle"
When you get on this site you realise all the big posters know each other and it's pretty difficult to get in on a community like that. That's discouraging, but unfixable.
Edit: Also, discord is not the answer to all our problems, that place is a hellhole.
Issue with the bolded is "how many people are going to be using it, and how often?", if I do make it (which isn't hard). Making it is easy, but are a lot of you going to use it?
If you guys are going to use it regularly, then it may be worth a shot. Otherwise, you're probably better off in the other areas (including Free Design).
