Difference between ACM's print and online memberships I would like to inquire about the difference between ACM's SIGACT online membership and print membership.

Background:
I am a sophomore computer science student interested in computing topics with emphasis on mathematical rigor, particularly, computational complexity theory and quantum computing. Subscribing to prestigious ACM gaining latest developments in the field and a chance of connecting to others seems promising.
ACM SIGs (Special Interest Groups) generally publish things like conference proceedings and newsletters. A print subscription implies that they are sent to you in print, usually a few times a year. An online subscription gives you access to the same materials only online with a login. Other than that, the memberships are the same.
