Description

Change the FTC kickoff location link from Walgreen Drama Center to the NC20 parking lot in front of G. G. Brown, the building in which the kickoff events will actually take place.
Remove the "tour U-M robotics labs" feature from the FTC kickoff page, as this might no longer be practical.
Replace the robotics major announcement on the homepage with a recruitment announcement for visibility. It includes the mass meeting time and location as well as a link to the interest form---essentially what we tell Festifall visitors. Since we are listed as a Festifall organization, I anticipate that our website traffic will increase, and not all website visitors will talk to us at Festifall. This announcement enables those visitors to join us.
