GeoChat allows you to control almost all functions via text messaging.

You can always send “help” to get reminders of these to your phone.
All of these commands work equally well on twitter, SMS, or email
Geochat has many ways of doing most of the operations through the mobile phone, targeted for different audiences.
Best of all, you can combine all of these syntaxes, or you can start with the basic syntax and slowly incorporate more advanced commands as you learn them.

If you are a new user and you have little experience with SMS, please read Basic commands reference.
If you don't like typing long commands and you think you can remember two-letters commands, try Intermediate commands reference.
If you are a techie or geek, you know where to find symbols in your phone and you want to send very short commands, you should use Advanced commands reference.
