Vtwitter
A Zimbra Zimlet that lets you send messages from the Zimbra email client directly to your Twitter Account.

Here is a new client for sending tweets from Zimbra email. Zimbra's website claims they have 6 million + users on Zimbra now. Some of those must be using Twitter (you would think anyway). Here is a copy of the release on their blog from the developers at VisionTEN :

"Twitter is a new microblogging and communication service by Obvious Corp. that has been taking the Internet by storm. There are many channels (blog, web, SMS, PC, Mac, Browser, etc.) that Twitter can be used from but we found there was not yet a client for the Zimbra Collaboration Suite (ZCS). We decided to build one. Today we are releasing the initial version of Vtwitter to the community. Vtwitter gives the ability for users of Zimbra email to send update messages to Twitter directly from their email in Zimbra. It is packaged in the Zimbra Zimlet format for ZCS administrators to be able to install it quickly and easily.

Vtwitter is released as open source software and the code will be available to anyone that wants it. We have set up a Vtwitter project page for more info, licenses, downloads, source code and documentation. We will maintain the app / source code and provide periodic releases to the public but we encourage everyone to make suggestions, comments, report bugs and submit ideas (and code) to make it better.

We have set up a dedicated Vtwitter discussion forum on the Twitter Community site over at TwitTown. Please direct any questions, comments or support issues there. There are some screenshots in the Vtwitter User Tutorial for those interested. Happy Twittering!!"
