Lets see if youre understanding what Twitter is.
On Twitter you are NJLovebus
When you post to Twitter (Called a Tweet) it is an announcement to all YOUR followers.
 
I don't follow NJLovebus, so I'll never see your Tweet. I only follow SJVWC, SJRA, Lemorris, Alex from Ice Road truckers and Dubs on the Boards
If they Tweet, I get it on my phone & email.
Only people who follow NJLovebus will see what you send
It's not that I dont love you, I just hate twitter. I use it only to follow announcements of the groups I belong to. (And Alex from Ice Road Truckers 'cause he's a scream!)
BUT, like you,  I know the value of getting the word out. So when I became President I obtained SJVWC as a twitter name. 
I Tweet all of the events, day before & day of. 
I also opened the Facebook Group SJVWC. It works like Twitter and I can announce events. The difference with the Facebook Group is any member can announce there. Twitter is accessible only by the president. Not because I want it that way, but because I was the only one who showed interest in it at the time I opened it.
So what exactly are you trying to do with Twitter?
