Is there anyway to send texts from your computer without like mobile cell modems or sending devices and stuff so I can have like a list of people and send them jokes or something you know... i know theres alotta programs but they dont work anyone know of any that work or any way of doing it with like PHP or Javascript or java or something ... i'd appreciate any help

Most providers offer yournumber@service.com email address for their customers. You can simply send an email to that.
You would have to be sending very short jokes though, as text messaging is limited to 166 characters including the subject I believe.

well I was hoping to be able to send to like any cell phones w/o having to try to figure out who the provider was
