You can choose to pay a cheap price up front to help support the development of the product, or you can wait until a more polished version of the product becomes available (and pay a bit more once it's ready). I won't say too much more here, just go over there and have a look.
This blog is a meander through my interests in and around the world of independent roleplaying. Due to spam bots I authorise people's responses to the posts here, so if your reply doesn't appear straight away, don't get frustrated. You might just need to wait a couple of days for me to log on again. If you're really passionate about your reply, send me an email and I'll make sure that your message gets through.
