Selling something for Fractional Mana?

How do we sell something for fractional MANA in secondary market?
I see many listings in the Listings section for less than 1 MANA (image below). But when I try to sell something it does not accept the decimal, so the lowest I can sell is 1 MANA not less.


Good question. I too brought this up last week. I think it’s important to be able to do now, and especially in the future if MANA becomes more “valuable”.
