If you're just beginning to work with mozilla then its recommended to start with a tarball from the most recent milestone build. Milestone builds occur on branches of the main cvs tree and have undergone QA and bug fixing to make them relatively stable. Later on, if you want to move off the branch and synchonize with the tip, do the following from the parent directory of your tree to remove the CVS branch tags from your tree: cvs co -A SeaMonkeyAll
For the most up-to-date tarball, grab the daily snapshot. Depending on the current state of the tree, this may not build, or it may be extremely buggy. However, it will update the most quickly with CVS.
To unpack a the .tar.gz file on windows you will need a win32 version of tar and gzip. These can be downloaded from Cygnus.

While you're waiting for the download (actually, ``before you even think about downloading anything,'' but who are we kidding) you should familiarize yourself with the developer documentation we have compiled to date.

The source is also available through several other methods, including CVS; see the Source Code page for details.

And finally, a huge thank you to all the people and organizations who made the initial release possible!
