How do you guys use Mercurial

Hi guys,

Since CodeIgniter moved from SVN to Mercurial and BitBucket, I got interested in using it for my projects as well. I've checked out several howto's on the topic, and it looks like a very useful tool for a more structured way of developing.

I've done some testing, and I think I'm understanding the workings of BitBucket. But I'm still a bit confused on how to structure my repositories.

What is a smart way of managing the current stable version that occasionally needs bugfixes, and a beta version where we develop new functionality. And say we start building a new forum module for the CMS and also a new photo album, do we then clone the beta repository to work on both new modules, or do we clone the beta repository twice. One for each new module?

In other words, I'd be happy to hear from you guys how you structure your repositories using Mercurial and BitBucket.

Thanks in advance!
