About the DA Masterlist Account: I do think this would be nice to have one, an visible masterlist can help if people trade/swap their charas and wants to keep an eye on trasition of the characters (like for be sure that people won’t scheme people into buying one non official fiskert or things like this)
If the account is something you end up planning to do is always good to remember that setting things up asap can help in the future, so you wouldn’t have to organize tons of charas in one go (I don’t really know if you’re working alone, but if you are I should say that you’re doing great into organizing things by yourself!)
