Important: SOME FOLDERS DELETED! Need advice!

So, I didn't know that deviantART has a limit of 160 gallery folders per group.  When I was adding some folders of Moana characters, I discovered that I had to delete folders to make new ones.

You may not know this, but I am not the original Founder of Disney Heroines.  The original Founder designed the gallery to make one folder per character.  I don't think there was a group folder limit, back then and the original Founder probably would never have guessed that there would be over 160 character folders in the future, anyway.

I am faced with a few choices:

Choice #1
I stick with 160 or less folders by deleting empty folders and just hope that there will never be more than 160 characters who have artwork in their folders.

Choice #2
I could include only the most relevant characters in the folders.  For example, there would be folders for characters like Cinderella, Judy Hopps, Belle, etc., but no folders for more obscure characters like Ursula Stanhope, Franny Robinson, Kanga, and others.  It would be a reliable solution, and we wouldn't have to worry about not having enough folders.  However, people wouldn't be able to submit art for wonderful minor characters.  In addition, I'd have to completely get rid of The Comic Character of the Month contest and possibly replace it with a Disney Heroine of the Month contest.  Unfortunately, it would take a lot of time and effort, and I would probably never be able to show contest results on time (plus I'd be stressed out! Ahh!!!).

Choice #3
I could change the entire group gallery structure and make folders based on films rather than individual characters.  For example, instead of having an Ariel folder, there would be  The Little Mermaid folder where you could put all TLM art (as long as it had at least one Disney Heroine).  It would be a very convenient layout, but it would be a big risk!  Disney Heroines' gallery is HUGE, so it would take forever to move thousands of submissions to new folders, not to mention coming up with an entirely new system of organization and rewriting the rules.  If anything went wrong with the transition, it could really ruin the group for a while.

Choice #4
We could upgrade the group to a Super Group, which would allow subfolders.  Although I would still have a lot to change and deviations to move, it would be easier than Choice #3.  However, it cost $59.95 (4,796 deviantART points) per year, and I don't think I coud reasonably afford it on my own.  If we could get a good donation fund started and/or a fundraising contest going, that would be great, but I'm not sure people would donate.

That's all I can think of right now.  We don't have worry about not having enough folders yet, but eventually we will have to make a long-term decision.

Let me know what you guys think.  I'd love to hear opinions and ideas!
