I know the whole idea for Public Mobile is to have the community forums as the primary support channel to keep the service low cost and no-frills, but having a relative real-time chat service would help. There's simply no way telling when a mod will get back via PM and posts, especially frustrating when there are relatively urgent issues (e.g. service got disconnected). However if you're at least queueing in an online chat, you have an estimate where you are in the line.
