Alright, people. I need one more new user to be able to double check 'column shifting'. Plus, you all were asking for something with this functionality, yet, it has not been used for anything that requires privacy or for much else besides. I am glad to say that it has been working properly with no major concerns.

Hey, can you show how you did this? I am curious how your program is informed of what account is logged on and how you sent information from one user to another (Or store that information on the network until that user come on).

@kiarocks, thanks. I fixed it. There were two places I had to inspect for his UserInfo to be found. I had forgot about the other one.

How? Why? I bow to you.

It appears that something has gone wrong with the program. My ID was -1 and should never change; yet, just today it appears to have changed to -92. Occasionally, also, it will assign the same ID to two persons (which I was sure I coded well enough to prevent from happening). I truly hope that I will not have to remove this scenario from the site (for several reasons). I will filter through the code and see what I can find in the meantime.

@JetLennit, see the discussion called 'On "Private Messaging" by danpost' at: http://www.greenfoot.org/topics/1938

I think either Greenfoot's UserInfo storage is not accessable (not because of you not being logged in) or a bug has cropped up within Greenfoot. It is acting very strange. Resetting fixes the 'not logged in' part; but an error occurs when you then 'start' the scenario (which never happened before).
