I have to admit I haven't paid a whole lot of attention to my Zidisha account. But every once in a while I do log in when I get notifications that I have received repayments, to see what I can do with it. So today I received a notification that I have received $1.10 back, and that my available balance is now $0.35. Really? So I log in and look at my transactions: How on earth did I manage to go negative? I am fairly certain I never bid more than I had in my account.
