I suppose virtueverse.com might work in a pinch. It has more of a bio page set up though. You could try Deviantart.com. You can post stories there, the same as any other art form.
If it's a hero, Crey Industries Hero Threat Database (which might not work) is the perfect place to post it. Otherwise, I'd just post it here.
I personally post mine up on DeviantArt as Fanfiction.
Eh, it's all congregated in one place and easy to read, so it's really not even nearly complicated.

Tropic makes regular postings to this forum about what's new there, so if you post something there, the folks here will hear about it and can read it there if they choose to.
I was wondering if there are any other sites where I could post my character's hero story. I will have to cancel my account for a couple of months, but I have much to tell those who wish to hear, but sadly once account is gone I cannot post on these forums.
Any information would be great, and thanks again.
