UserInfo IM

Instant Messenger with individual users. Live chat with "online status" indication.

Threw this together the past few days.

PLEASE READ THE FOLLOWING:

NOTE
* This is not a mailbox implementation.
* Messages are no longer available once a chat session has ended.
* Messages can be sent between 2 users if BOTH are paired with each other.

Can have 2 chats active at a time.

HOW IT WORKS, via basic example:
1. Both UserA and UserB are paired with each other.
2. UserA: send message to UserB.
3. UserB: receive message, send notification to UserA.
4. UserA: recieve notification, remove message.
5. UserB: remove notification.
6. Finally UserA can now reuse the message slot.

Each message can be of length 50 characters (may be increased to 62 in the future).
If you send 3 messages with the first 2 not complete, the 3rd will fail to send.

From what I tested on site, seems sending messages took ~2 seconds to complete.
(1 second for other user to receive, and 1 second to receive notification)

Basically have ~13 unused bits for each of the two ints in use (the other 8 ints are not used).
One string not used, may end up allocating 12 characters for each other string (making individual messages to have max length 62).
