"Come share your ideas for West Campus socials, parties, events, and concerns!"
The part in green is OK - "concerns" seems to stick out a bit as not being in the same league as "socials, parties and events."
You're American, so "Come share" should be acceptable. I take this to be an invitation for everyone to come and share their ideas with the Social Committee (or to form one) and say what they think about socials, parties, events; and to bring up any other concerns they have about social activities at the uni.
In short, it sounds quite sane. I might change it to:
"Come share your ideas for West Campus socials, parties, events, and tell us any of your concerns!"
