A script is a series of commands using a particular programming language that tells the computer and its applications what to do. If an application is scriptable, it will have its own set of commands that are available for scripting. To create a script, a script editor is typically needed. A script editor can usually show which applications are scriptable and what commands can be used with them. It is also a good tool for making properly formed scripts. Other programs such as text editors may also be used.

SMS stands for Short Message Service. It is a communication protocol that allows mobile phone users to send and receive short messages, which contain letters, numbers and certain characters to and from another mobile phone. This service is also called text messaging or texting.

Texting is now an increasingly popular thing to do, even in countries where sending text messages are more expensive than actual calls. One reason why people like sending text messages instead of calling is that because it is so non-intrusive and casual, particularly as compared to a phone call.

Particularly common among teenagers, texting is an easy way to communicate to someone else. It is easy and fast to send a text message to someone even if youa re busy doing something else.

Texting has also recently developed due to new phone models that allow users to ad emoticons or animations to the text and send them off, giving them an idea how to feel about the text message they received.

Because of this spike in popularity, there became an increase in the sales of mobile phone models that are capable of handling a huge amount of messages. The charges involved with texting have also increased, as some countries consider it as a non-essential thing.

As a reaction to that, one new service being offered by several websites to Internet users is the free Short Message Service (SMS). The service is typically used by visiting the website concerned and keying in the SMS message and the mobile phone number of the intended recipient. Some sites require additional information such as the email address, name and mobile number of the sender. Other sites are free for the first couple of messages, while succeeding messages would require a reply from the recipient.

More liberal provision of the free SMS messaging service has now been to allow users of the service to add free SMS messaging box to their MySpace profiles, websites, or blogs. Such messaging box would allow not only visitors or viewers of a user's MySpace, website, or blog to utlilize the free service, but will also allow the user to receive SMS message through his Myspace, website, or blog.

The addition of an SMS messaging box is basically done through text scripts which the service providers themselves have created or which they have allowed users to create. Roughly, the text script commands the application for the Myspace page, website of blog sites to incorporate the SMS messaging feature of the providers website, among others, a method similar to linking.
