General rules:

The Qosts species is currently closed due to edits to designs, lore, etc. It will be open for a brief amount of time in the future so stay tuned.
Please, ping Stevie for your Qosts designs to be officially put in the Qosts characters list
For now, please avoid gifting, selling, and/or trading MYO tickets or Qosts characters to anyone off of Toyhou.se.

MYO Tickets:

You can make your own Qosts using a MYO(Make Your Own) slot. To get a MYO ticket, you can either wait for a new raffle, wait until the species is briefly open, or wait until Stevie finds the time to give all members of the Qosts world 1 free ticket.

If a MYO Ticket's owner changes, please, inform Stevie or a mod (there isn't any right now) so the masterlist can be updated properly.
You can gift, trade, or resell Qosts designs but MYO Tickets can only be traded or sold if you purchased it or traded for it. (Free member MYO tickets are an exception)
You can trade a Qosts for another Qosts, for a different species, or for art/writings.
You can only sell a Qosts if it's the first MYO ticket you got for joining the Qosts world or you paid to get/make it (purchased an adoptable/MYO ticket)

You can ask for customs by any artist as long as you have a MYO ticket.
