Hey so I haven't been on here in a while but now that I am I should tell you guys about this cool website called CharaHub.
CharaHub is a website where you can post your OC's and write full bios for them and answer questions that make you think about things that you hadn't before, regarding your character.
Not only does it make you go in depth about what your character is like, but it's a great way to share and organize your OC's. I'm someone who makes OC's at a pretty rapid pace, only God knows how many I have now, if you're like me you need this website to keep track of all those dang OC's.
With a free account you get to post up to 100 characters, you can buy more space but I doubt you have that many characters.
Lastly you can share what you're character looks like by uploading a picture, so if you haven't drawn them yet here's your chance.
I've posted 10 OC's so far if you want see here: charahub.com/user/zekroraptor
Go ahead and try it.
PS, the section titled "Questions" is a long list of questions regarding your OC's interests and details you haven't thought of before, but be careful because when you hit save it hits a 404 page for some reason (at least for me it did, maybe it'll be different for you).
