I'll keep this one shorter. Maybe
1) Regarding emails versus texts - again, she said that you need to think of it like dating - email's, unless it was formal event of some kind, is a bit much for a mixer - this is an area where she said a text comes off as more of a casual, play it cool, no big deal kind of thing. Sending an involved email for a mixer would come across like a guy asking you out for coffee and showing up in a suit with roses and candy - it's overkill and too formal for the event. Maybe that's just her and other social chairs would feel differently, but for the simple mixers....keep it simple. Don't sweat it this much.
2) When in doubt, start with the dinner. If they like your guys, they will stay and hang out. Move to a mixer for the next thing.
3) I don't mean to suggest that guys in relationships can't be social (she mentioned her BF did a great job of going to socials and being social while respecting her), BUT there were times when they did things with some fraternities and if a lot of the guys had GF's they seemed to stick by the wall and not be terribly social. Just be sure your guys understand that all they have to do is be friendly and meet people- regardless of their status.
4) If the mixer thing is stressing you out (in terms of how to ask, when to ask etc.) she emphasized starting with big "invite everybody" parties and have a lot of them. Rent out a venue if your house is too small or use a live-out. Takes the pressure off of you in the sense that no one has to say yes or no - they just have to show up. It doesn't have to be a theme. Just invite people. If your guys have GF's have them invite their friends over. Have date-dash cocktail parties or dance parties. Again, keep it simple and don't sweat it at first.
Okay, that wasn't much shorter. Sorry. I'm an English teacher. I can't shut up.
