~Greetings!

And welcome to the Isaac Asimov Role Play Forum!
You can do basically what you want here. You can be the characters from his story, or you can interact with them.
You can make your own setting, or you can make your charatcer take the place of Asimov's in one of his novels. Just make sure to respect each other, respect Asimov and his stories, and follow the TOS.

((And please make sure the book has the same basic outcome. razz No changing history!))
