With the addition of Gamma, things have only gotten more confusing for new players. It's so hard to explain, many longtime community members need a thorough explanation of how the current economy on the server works. Simply put, /bal is a mess because it doesn't tell you which economy it is displaying for.

My idea would affect both parts of /bal. By that, I mean checking your own balance, and the balance of someone else. All you would need to do is /bal (Alpha/Beta or Gamma). Therefore, you can check your A/B balance while in Gamma, and vice versa. If you do just /bal, it defaults to whatever world you're in.
The second part of this would be when you log in. Instead of displaying bal as it currently does, it would tell you the amount of Meebles you have in A/B on one row by saying "X Alpha/Beta Meebles," and then have "X Gamma Meebles" on a second line.
Hopefully, this will make things a bit easier to navigate. In addition, this would partially solve the problem of people coming back to see their balance is cleared from the Gamma release. There's not too much to say about this, so basically it would just allow you to check your /bal for both economies without changing worlds.
