There actually are some other icons around! But xD Given that they only came about as part of a very closed beta before the site recode, I'd appreciate a feature like that too! (+1)
Just a thought, being able to pick out of a small selection of custom icons if you pay for a years worth of premium or something. Kind of like how Art Fight works.
Obviously no crowns, since those seem to be moderator/admin symbols.
Perhaps even just a small list you can choose from, like a Heart, a Rocket Ship, etc.
Motherbeast While I could see the reasoning behind those, I feel like the writing one would just lead to some users spamming Literature posts and the other will end in complaints of favoritism, since a lot of popular names will be the ones with it.
Just having a select few for any user to choose from is a fair and even ground for all users.
