I got new badge ideas. (I'm sorry if they are bad, but I'm suffering from Imagination block, where you lose creativity for a while.) Here they are:
Solar Empire (9,000 posts)
New Lunar Republic (11,000 posts)
Eclipse (15,000 posts)
Nightmare (18,000 posts)
Daymare (20,000 posts)
Demi-God Pony (100,000 posts)
For the symbols for the badges (In the order of the list above)
The Solar Empire symbol
The New Lunar Republic Symbol
The Eclipse Luna causes in Twilight’s Flashback when Luna became Nightmare Moon and Celestia Banished her.
(Basically the image above, but make the dark circle more moon-like)
Use Nightmare Moon/Nightmare Night symbol
Make a symbol like the one in Nightmare Night, but use Solar Flare.
Look Up Solar Flare before you do.
Last, but not least, use the MLP Element of Harmony table thingy.
