Persuading people to pick up the frickin' phone...

When I want to contact a large number of people, I:

1.) I post a memo on our online forum (if it's Sigma Chi related)
2.) Text message
3.) Call and/or leave voice mail
4.) E-mail or instant-message
5.) I use word of mouth, tell everyone to spread the word.

Repeat the above steps, lol at least twice.
