We're spending roughly $400/year to keep our site up and running.
Last 7 years, we spent our pocket money to keep the site, but the things are getting difficult. So, to make those money, we decided to open our store at CafePress.com.
We are selling T-shirts, mugs etc. there, each marchant gives us $1 of revenue. We'll use those revenue only to keep our site, nothing else. We understand this decision sounds a little bit greedy, or far from nonprofit, but that is the only way to keep our site lasts longer (We even need to make $50 to keep this store, but this is another story. If the Cafe Press rejects to keep this store, well close it).
Thank you very much for your support and understandings!
