We need volunteers and look forward to your participation. This page is about becoming a savannah hacker (i.e., a savannah website administrator) and help savannah.
For communication with other savannah folks, see SavannahHackersCommunication, which includes mailing list info.
Read HowToGetYourProjectApprovedQuickly, which explains in detail what a submitter should check, but also serves as a guide for savannah hackers reviewing the project. See also Mario's guide for reviewing projects.
Read the CodeOfConduct to understand how to communicate with our users with politeness.
Pick a pending (non-assigned) task in savannah's task list: https://savannah.gnu.org/task/?group=administration
Read it, then write the answer that you would make as the savannah reviewer.
If you wish, you can use the savannah hackers' macros file for emacs or vim (savannah.[el|vim]) to help in writing your answer. It is good information to know in any case. See:
git clone git://git.savannah.gnu.org/administration.git ls administration/approvals/
When your answer is ready, send it (with a link to the task) at firstname.lastname@example.org and one of the current savannah hackers will answer as quickly as possible.
Another solution is to post a pastebin (http://pastebin.com/) of your answer and the number of the task on irc (server: freenode, channel #savannah) and wait for a savannah hacker's answer.
When accepted, you will be made an administrator of the administration project, which will enable the "Become Superuser" option in the left-hand menu.
Working on Savannah Internals
The above is about helping as a Savannah administrator via the web interface. If you are willing and able to hack on the Savannah (Savane) implementation itself, see the SavaneRewrite page.
