Check out the Inauguration schedule

President-elect Barack Obama is known for his love of text messaging, and that figures in plans for his inaugural.

The Presidential Inaugural Committee made it clear Wednesday that it expects large crowds for the inaugural ceremony, and it strongly encouraged those who plan to attend to keep in touch with its Web site for updates on transportation and pedestrian notices. Even those who stay in their own cities and town should tune in to learn “ways you can participate,” it said.

The site is www.pic2009.org and it can be accessed by texting the word “open” to 56333.

Inaugural events include:

• Sunday: Opening public ceremony at the Lincoln Memorial, 2:30 p.m.
