Dear Readers, since I did not meet my fundraising goal a few months ago in the Spring, and currently am facing a bit of a financial burden that may hinder me from working on this website for a while within a few days, I thought it would be best to appeal to your help to meet my goal at this time. My work here depends on your help, so if you find it beneficial or of interest, please send your financial support. It is greatly appreciated.
Goal: $220 or $3000
