There is always room for improvement. If you have an idea or find any mistake, please let me know: email@example.com
The next best and easiest thing you can do is just promote the sheets and this page, e.g. tell your friends, recommend the sheets in online-forums or link www.sunrainstudios.com on your homepage, and so on.
Developing these sheets costs time (well, duh!) and resources (software, hardware, prints). If you want to support the development please feel free to donate money via PayPal. (Hey, this was worth a try...)
If you like the sheet you can help to make it more popular and increase its distribution, eg. simply tell your fellow players or mention it if online forums, or link it on your homepage. You can even hotlink an icon using this url:
