Topic: very new - need help!

help!  I am brand new to this program and have no idea what to do! i am looking for basic instructions on how to use this but i can't seem to find them (i very well could be missing it staring me in the face!!

i am on a mac -
i just downloaded the iphoto export and thought i uploaded a album but i dont know how to view my account(s)

how do you make more than one album to display?
can you lock albums?

(i.e. i will be showing clients their proofs - will i have to send them to a main page or will everyone have their own online viewing address?0

thanks in advance for the help.. as you can tell im very new!!
