I’m sure you can find instructions somewhere on this forum. Of course, there are instructions also on Patreon. It’s just that you mentioned that you’re too reluctant to re-subscribe.
Isn’t that sigil free, and freely available, both on Sapien’s Instagram channel and in that thread?
Quite a number of fields have various forms of protection. As a recent troll-ish member of this forum pointed out to us, even with protection, that’s (sadly) no deterrent to people inappropriately sharing Sapien Med’s hard work.
