Twinstars, I have to add a disclaimer to your "good numbers" criterion. You should also consider the age of the chapter. If a sorority just colonized on a campus (especially if the group was a local sorority) it may very well have lower numbers for a year or two - not because it's "worse" but because it hasn't had as much time to establish itself. If it's really small compared to other chapters (say, 10 sisters where most chapters have 100) then be careful - a group like that may be on the verge of dying out - but if it's only, say, half the size of other chapters, don't hold that against them.
Happygurl, when I joined my sorority, somehow I knew it was just right. I'd dropped out of formal rush, interested in joining a sorority but not sold on any of the nationals on my campus. My (then local) sorority held rush the week after formal rush, and somehow I felt these women were my sisters even before I got my bid. The best advice I can give you (trite as it sounds) is to follow your heart. And good luck!
