First: THIS WILL NOT WORK WITH mIRC 7.X!!!!!!!
The encoding to make the signatures for OAuth Authentication require the unicode character "pairs" that no longer exist in mIRC. At some point I will adapt some code for this but it's not really high on my list. Perhaps I'll get lucky and Khaled will add a proper hmac-sha1 identifier as nearly all other languages have.
Anyhow, this script will only work with 6.3x, due to a lack of a sha1 identifier in older versions.

To the script::
This script will allow you to update your status with your "own twitter application" information.
The result will be a twitter update like this:

"Testing mirc script"
"35 minutes ago via YourAppNameWillBeHere"

In addition to your app name being posted, this is quite an awesome spammer because you can associate whatever link you want with your appname.

START HERE:

* Go here -->> http://dev.twitter.com/apps/new
* Fill in all the boxes
* Application Name: Will Posted after each tweet (ie via Application Name)
* Description: Anything you want here.
* Application Website: Will be linked to the application name in each tweet. (spam your website here)
* Anything you want here. Only shows on the apps page.
* Application Type: Click "Client".
* Default Access type: Click "Read & Write".
* Application Icon: You can skip this for now.
* Enter the Captcha
* Click "Register Application"



Now you have registered your first app
You can always go to http://dev.twitter.com/apps/ and see your apps.

Now you just need to get the keys and secrets and put them in the script:

* Copy the code from this page and paste it to a new remote in the mIRC script editor. (keep this window open)
* Click on your application (if needed)
* Scroll down to Consumer key
* Copy the key and paste it over top of "PutYourConsumerKeyHere" in the consumer_key alias at the top of the mIRC script.
* Scroll to Consumer secret
* Copy and paste it over "PutYourConsumerSecretHere" in the consumer_secret alias.
* Now - On the right pane of your applications page - Click "My Access Token"
* Copy the token under "Access Token (oauth_token)" and paste it over "PutYourOauthTokenHere" in the oauth_token alias.
* Copy the token under "Access Token Secret (oauth_token_secret)" over "PutYourOauthTokenSecretHere" in the oauth_token_secret alias.
* Save the script with a unique filename and you are ready to tweet
