I don’t think there is anything out there that you could put out on the internet and not find a group of people that have been there, done that, and are probably still doing it. BTW, I was totally into medieval swordplay at one time – The Society for Creative Anachronism and all that. I still like to fight with swords but now I rarely have time.
I thought I was the only one fascinated by antique, Victorian taxidermy dioramas and then I met someone who was into the same thing! I later found out we had many more odd things in common too. It’s wonderful when you find someone like that!
