first- for my queuing system it seems to bug if someone logs out while queuing which well I expected. If they do let's say I have a list of 2 players. If 1 of them has been logged out(deleted) would they than equal to null? Than I could check for a null.

Second question: how can I use arrow keys on webclient? As well as zoom it in 200% if it's at all possible.

Mobs don't automatically delete themselves when you Log out. Only clients do this. If you are specifying that a mob should be deleted on Logout, any references to the mob will be nulled out by the del instruction.

IMO, you should never use del unless absolutely necessary. It's slow and it hides memory leaks and design problems.

yes i am aware of deletes problems.

and i know i make them delete themselves. I guess what i should do is just make them equal to null instead of del

The best practice would be to remove the mob from the queue when its user logs out.
