Don't know if this the right place to ask, but "Does Armory not support multisig addresses to send BTC to?"
When I try to send BTC this address (which is a multisig address): 39wbuEjp3mfFAB3bTjmkFB69XAmKYRMq5i ,then I get error "You have entered one invalid address..." and after that "Address1 is for the wrong network..."
Armory is version 0.90-beta on 64bit Kubuntu12.04
This should work with 0.91. Key feature is "enabling P2SH addresses".
