Hi CMC,
During big holidays (like today) and weekends, you keep dropping UNO to the low volume chart. Actually, volume today for UNO across MP and Cryptsy exceeds your .5 btc trade limit, but you don't seem to combine the volume of our most active exchanges. Many days, MP is very often biggest volume exchange.
So that your users are not misled about UNO, I suggest combining volume across our biggest exchanges. Maybe a brief grace period for established coins could smooth out these fluctuations (24 or 48 hours?).
Anyway, Uno is already nearly 1btc today on a big holiday, but remains on your low volume chart.
