Hello all,
I want to apologize about the server issues the last few days that are preventing new invitations from being issued between users.
We use Google App Engine as the server for WordWise. Google performed routine server maintenance several days ago. Usually this has no affect on apps that run on App Engine, but currently our best guess is that Google's maintenance did something that affects the part of our server that receives and processes invitations.
We're working to resolve the issue, so thanks for being patient.
