Hi!
I just wanted to add my two cents. I am (well, I've graduated already) a member of Phi Eta Sigma and Alpha Lambda Delta. At Cal State U. Long Beach, the two honor societies are combined as one (PES-ALD). In case you didn't know, Phi Eta Sigma used to be a fraternity, turned men's academic honor society, which went co-ed in the '70s. Alpha Lambda Delta used to be a sorority, turned women's academic honor society, which went co-ed in the '70s. Both were founded at the University of Illinois. Because some campuses had both, they essentially compted against each other. Instead of getting rid of one, they just decided to join forces on my campus. That explains the long name.
During my collegiate years, I was Secretary, President, Senior Advisor, President and Senior Advisor. Obviously, I really enjoyed my time in PES-ALD! (Yes, for those of you doing the math, it took me 6 years to get my BA. No, my grades had nothing to do with it.

)
Many of the people who replied to you called it a "resume filler."

That's one thing we specifically tried NOT to tell our new members. Of course, each campus is different, but, on my campus, we had social events, did community service and supported the university.
As with most things in life, it is what you make of it. I had the wonderful opportunity to attend the National Alpha Lambda Delta Leadership Workshop in St. Louis a couple of years ago. What fun! (I still have a Louisiana State U. t-shirt from the t-shirt exchange!!). It sounds as if you don't have an ALD chapter on your campus. Too bad, it's a great organization.
National PES, I'm sorry to say, is still quite old fashioned in their operations (heh, I bet you filled out that little membership slip eh? I once had to call a lady from the national office to ask if we could photocopy them. She said we couldn't and added, in her pretty southern drawl, "We've been doing it that way since 1934."

Meanwhile, ALD will let you e-mail a list of new members to them.) At any rate, Phi Eta Sigma does have a convention every two years I think.
I think it's a great way to get involved. Try running for an office. And hey, you can check out my chapter's website at

Congratulations on your acheivement and welcome to Phi Eta Sigma!
