You should set the masternode in masternode.conf, not ida conf..
Open your explorer, and type in %appdata% then enter. You should get a list of folders, where you also find IDA's config folder. In there you find the files you need to change.

Not that we are aware of.. I don't even find those two listing IDA.. you got a link perhaps?

Nowhere to trade IDA now after altmarkets.cc went down.. We're approved into Bisq, but it is probably too difficult to use for many.
Looking for a new exchange so we'd be most happy for any inputs.
Being so small though as we are now it can wait until our wallet updates are done in my opinion.

Yes it is the same. As I said we are approved, but have to wait for the next code update of Bisq before you can trade IDA there.
Bisq is totally decentralized, also in the listing process, which happen on their github.
