In almost all cases, my ID/handle/username will be
cosmicbun11. I have accounts on many sites, in varying activity. Here is a complete list of links with explanation. (may not be up to date; check post date)
Any direct inquiries should be made through email. Contacts through social media may be intermittent; you may not get a response for a long time, if at all.
Come back later to see the links in all of its glory.
