these might seem like a dumb questions in comparison to all the programming stsuff but ....

when i set a buddy pounce and ask it to open a im window when a buddy signs on, sends a message, whatever- does that open an im window that my buddy can see or am i the only one to see it? i realize if it set it up to send a message it would go to them but can the buddy i've "pounced" see any of the other alerts?

Also, i thought pidgin was able to show if a user was signed on as "invisible"--- will i see that?

And last one-- if someone has blocked me will they just show as offline or invisible or not at all? like with aim if I block someone they should just see me as offline- right?
