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.
Report bugs to masterchain@bitmessage.ch (please text only).

I created a MSC selling offer at address 12QcQmKr7TaPNSHV4g2Nts3nvQAHwKN9cF, but this address does not have any Mastercoins, why still can send bitcoins? I lost 0.0000543+0.0001086=0.0001629 BTC!!! Is this a bug? People can create a sell order in any Bitcoin address even if no Mastercoins in it?

Can anyone tell me whether it is a bug or not? How can I get my BTC back?

It should be a bug of the software you used in creating the selling offer, but you cannot get your BTC back because BTC sending is non-reversible.

I did not use any software, I just use this website: https://masterchain.info/.

As you said, this website(https://masterchain.info/) has a big risk to trade. Because people will lose their money always without any prompt.

The it's a bug of that website. Maybe you could report this to its owner. This kind of offer should be treated as invalid and should not let it happen. The BTC loss is minor, but the problem is that the invalid offer will ruin the blockchain and increases the trouble in parsing later.
