It's will be good, if WI will have one very important feature - email notifications about changes in the issues.
If someone assigned bug to me, he must notify me by mail, irc or some other way about it.
Of course I can check WI self, but, project is not very active, and I not check it every day, so, user can wait long time before he will get some response
I can see, that email notifications already announced, so, waiting.
Will be glad to be a tester
