I don't know if this counts, but I found an online version of a magazine I have read for many years and then lost touch with.
It is a really informative publication for Witches/Wiccans/Pagans.
I know it is not strictly Otherkin, but I was so excited to rediscover it again that I thought I would share it with you just in case it might interest you.
It is subscription only, but every good thing must be earned or paid for. It's called The Cauldron, and was published quarterly, and can now be found ONLINE! Hurrah.

Here.
