How to become a savannah hacker (ie a savannah's website administrator) and help savannah.
Read "how to get your project approved quickly", which explains in detail what a submitter should check, but also serves as a guide for the Savannah hackers reviewing the project: https://savannah.gnu.org/maintenance/HowToGetYourProjectApprovedQuickly
Subscribe to the savannah mailing lists. savannah-hackers-public (http://lists.gnu.org/mailman/listinfo/savannah-hackers-public) is the primary list. savannah-register-public (http://lists.gnu.org/mailman/listinfo/savannah-register-public) gets the exchanges between people registering projects and savannah folks.
Pick a pending (non-assigned) task in savannah's tasks 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 hacker's macros file for emacs or vim (savannah.[el|vim]?) to help you writing your answer. It is good information to know in any case. See:
tla register-archive http://arch.savannah.gnu.org/archives/administration/ # may be long: tla get administration@sv.gnu.org/infra--main--0 savannah-administration ls savannah-administration/approvals/
When your answer is ready, send it (with a link to the task) at savannah-hackers-public@gnu.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.
We need volunteers and look forward to your participation.
