we do a lot of movie nights, pot luck stuff at the houses, go out for ice cream, etc......i was new member coordinator and i made sure to invite old girls to the meetings, too.....that way, we're not separated as "old" and "new" for too long. incorporate both groups as much as you can in their process.
the new new member coor. had the girls make a list of 10 things we didn't know about them and put a picture of them on it.....it's up right by the front door so everyone can see our new gals, learn stuff about them, and see how proud we are of them to show them off!
i don't know if you do a retreat or not, but we have our "new member retreat" about 2 wks after formal recruitment....it's just alpha gams and it's soooo much fun! make up agd songs to current songs, play silly games, and we each bring something significant to us and explain it (the emotional part of the night)....my favorite time of the year.
