I think LucraFlex (Lucra being a car.. but hey) its a play on words.

Lucrative and Flexible. Or MolyCoin, as in chrome moly. Strong and flexible. For some reason I feel like a car today.
Lucra is the plural of Lucrum so it actually fits better... Because a community is a plural... Many coins are plural...
LucraFlex
Maybe just Lucra... Short and sweet... Easy to remember...

Lucra2.0
LucraBeta (Beta is the second of any series... So second gen) Plus we could do a simple modification to our logo and change the D to a B
Someone sees where I was going with this....
