The document introduces usage of PNS Web interface.

Here are the concepts of user channel and tag channel, which must be clarified：

• user channel is named by the unique uid of mobile device. PNS will sub the uid automatically when the connection is setup (sub means join channel)
• tag channel is the mobile clients group(uid group) setup by sub API. for instance, a client sub “location:beijing”, then it will join into channel “location:beijing”, when push messages to “location:beijing”, the clients in group of “location:beijing” will receive messages. Tag channel can be treated as a group for tag push.
