I think your tables in the UC did alot of good as well. You might try getting a table once a week or so and try to recruit new members.
During the first few weeks of school maybe do it a few times a week. Anything to get us seen will help.
I’d also like to see you guys set up tables on open house days again. That one day you happened to have a table during an open house I think you got a ton of visibility to the incoming class and that will help more than anything.
