...when I go to my account and then to "edit comic", I guess that I should upload a html-file where the character-bios are.

But how do I do that? How do I even make a html-file to upload? Can I make one at drunkduck or do I need some kind of program to make it? I kinda don't understand html sometimes, some help would be great! And i hope this is not the wrong forum to ask in...
