Hi Paul, > Is there a way to retrieve the consumer keys for the other Twitter > account I own without registering an app?
Yep, if you use that script given previously, just login to the other Twitter account instead (with the same consumer key/secret. This will give you a different pair of tokens for the second account. Initialise as in tweeting example with the new token. Basically what you're doing is authorising the same app for both accounts. - Paul
