John Joseco who has been the person behind many of our favorite pony drawings over the years and my colleague on Ask Gaming Princess Luna and Hunters of Salamanstra has recently been hospitalized for an illness affecting his drawing arm.
 
He’s had to undergo surgery and was even at risk to lose his drawing arm altogether! In response Jen (who does a great fan voice of Celestia in the fandom) and myself have started a fund to raise money for his medical bills. I really hope you guys can help to get him back on his feet!
