Update
For the foreseeable future, this is a deadend project. A long time ago, Twitter disabled XMPP/IM communications, and with the recent announcement of cutting SMS push, looks like they won't be enabling XMPP anytime soon.
Since that was the primary drawcard of MahTweets, I'll call it dead until significant changes happen at Twitter, or another microblogging service arises with a
decent API (I'm looking at you plurk, just shameful!)
Welcome
Mah Tweets is a Twitter client with a difference.

In addition to using the regular Twitter API, it uses the Jabber protocol to get instant notifications from Twitter. This also means it's capable of using Twitter's Keyword Tracking notification services.

Requirements
OSX Port Requests (Help Wanted!)
A number of people have requested an OSX Port of MahTweets, this is technically feasable, however we require collaberation with someone with a certain skill set to make this happen.
Give us a shout if you have any of the below:
- Experience with C# (preferred), Java, or other C-Style OOP Languages
- Experience with, or willing to learn
Cocoa# or
Gtk#- Understanding of Threading and Eventing models.
We're in the process of restructuring MahTweet's internal code to facilitate multiple different types of interfaces, so effectively you'd have to implement just the UI specific code (eg: clicking a Send button = call MahTweets.Send(message);) and do any adaptations to suit any implementation-specific quirks.
