I can appreciate the desire to be creative with a suggestion of themes. However I agree with Mick about the general diversity and freedom we usually get in our exchanges and that being a strength. I want to stick to the open themes because that's what makes the rounds so interesting. If someone wanted to do their own theme then go for it like when rst and Ingo did that really cool dual image postcard a couple rounds back. When groups get into themes sometimes it feels like people don't want to think about what to photograph and this makes it easy in not choosing. This statement is in no way intending to offend by the way. Just my 2 cents.
