Why do you need donations?!
A lot of time, effort and money goes into Kokoro no Naka. The webspace alone costs around $17 a month, being the page is so large it spans two servers and it's still having bandwidth troubles due to people abusing it. I put in an average of 2-6 hours a day working on the site, trying to get it to be the best I can and processing requests from people for images or information. It's a lot of work and a lot of responsibility and being I am currently very short on cash and this is an expencive hobby, some suport would be nice.
Multiple ways. Easiest and fastest is VIA PayPal. Even if you never use PayPal again, you get $5 for signing up.
If you don't have a way to sign up for PayPal or don't want to, there's always sending through the mail, which is slow and iffy, but do-able.
And if you have no way to do either, you can email me and we can figure something out.
If you have any questions on this program, feel free to email me at firstname.lastname@example.org
