new chapter

So Alpha Sigma Phi is coming to Oklahoma State and I got offered to be apart of it this fall. I wasn't very interested in Greek Life until I got this offer, but now I think it's pretty cool that I could start off my college experience by being apart of its first impression on campus and not have any past events affect how people view the chapter, whether it be positive or negative.

My question is about how chapters already on campus view new ones? Do they look down upon them? Do they help them out? Other than grades, what's the best way to make a new chapter stand out and build up a good reputation for itself?
