Registration
To use TXTmob, you first need to register your cellphone number and service provider. We also ask that you provide an email address where we can reach you. After you register a new cellphone, we will send you a txt message containing a secret code. After you receive this message, you must enter the code at the TXTmob website in order for your phone to be activated. You will be unable to send or receive messages until this step has been completed.

Groups
A group is a collection of TXTMob members who share TXT messages via cellphone. There are currently two types of groups:

Public: a public group is one which any TXTMob member may join.
Private: membership in a private group is limited by the group's administrators. When you first join a private group, your membership will be listed as "pending." Once an administrator upgrades your membership, you will be able to send and receive messages. Depending on the group (and the personalities of its administrators), this process can take anywhere from a few minutes to several days.
Secret: secret groups are similar to private groups in that membership is restricted by the group's administrators. However, membership in secret groups is by invitation only; secret groups do not appear in group directories and uninvited members are unable to sign up for "pending memberships".

In addition, groups can be "Moderated," in which case messages may only be sent by the group's administrators. An unmoderated group, on the other hand, allows all group members to send messages to the group. In any case, TXTMobbers can only send groups of which they are members.

To view information about a group, click on the group's name.

Creating and Administering Groups
In addition to joining existing groups, TXTMobbers can create their own groups. When you create a group, you are prompted to give the group a name and description, and to decide whether the group will be private or public. You will also indicate whether the group will be moderated. Once a group is created, you will be the group's administrator, which allws you to change the group's name, description, and type. Administrators can allow other members to become administrators, and can remove people from the group. If your group is private, you can also approve pending memberships.

To create a new group, click on the "create a new group" button.
To administer an existing group, click on the "administer group" button that appears next to the group's name.
If you are a group moderator, you can invite new members by following the "invite new members" link on the "Administer Group" page.

Sending Messages
From the TXTMob website, click on the "Send a Text Message" link (on the profile page). This will take you to a page where you may enter a message, and select which group to send it to. Simply click the "Send Message" button, and your message will be delivered to all members of the selected group. Please note, you may only send messages to groups of which you are a member. If a group is "moderated," then only administrators may send messages to that group.

You may also send a message directly from your phone. Simply address your message to [GROUP_NAME]@txtmob.com.
To view all messages that have been sent to one of your groups, click on the "History" link next to the group's name in your profile page.
NOTE: if you want users to send messages from their phones, make sure your group name is short and doesn't include any blank spaces.
