Re: quote from grazcoin above (masterchain.info wallet/DEx)
It looks like you need to create a new wallet first and then search for your mastercoin/bitcoin address.
Once you find the address you can add it to the newly created wallet.
Are there any official instructions for beta-testers for the wallet and DEx, like where to acquire test mastercoins and where to report bugs?
No need to create a new wallet. It gets created automatically if it is not there already, e.g.the first time you click "add to wallet" on some address.
No official instructions as the code is still hot directly from the oven. Also being now in the revolutionary & chaotic phase of the development, things may change very fast. Whenever a beta stage comes, I will tag it as beta.
Testing - you are more than welcome. Just follow the tutorial and experiment.
General testing and testcoins - that's not me.
