Does anyone know Cashcraft's TOU?

Does anyone know Cashcraft's TOU regarding conversions? She has a large number of items for TS3 that I'd like to convert to TS4 for personal use, but if her TOU allows them to be shared, I'd like to do that as well so others can play with them (full credit for them to her, of course). However her TSR page doesn't mention if they're allowed or prohibited, and I've only seen one or two conversions in the wild with no mention as to permission. I don't have a TSR account to ask and I'd prefer not to get one, so if anyone knows, I'd appreciate it. 

Thanks!
