Things you should do if you are a Clojure Contrib committer:

• maintain your library and respond to questions/issues that arise.
• do your work on the master branch, or (if you are working on a significant chunk you want to keep temporarily separate) on a feature-specific branch that you create yourself.
• use the Maven Release option on build.clojure.org to make releases.
• coordinate with other committers before making changes to their libraries.
• accept contributions from others only if they have signed the CA (see http://clojure.org/contributing for the list) and if they submit a patch. 

Things to avoid:

• please do not push to the release branches (names like 1.2.x). The Clojure/core team uses these to make the official, tested release.
• do not take non-contributor patches.
• please do not take pull requests from contributors. Patches only. Yes, it is inconvenient. Sorry.
• do not change the version number in pom.xml - use the Maven Release process mentioned above.
• do not make a 1.0.0 release without full review and approval from Clojure/core!

Here's the process outline for what it takes to become a committer:

• Get your CA on file
• Join the clojure-dev mailing list
• Create a JIRA account
• Create a Confluence account as well if necessary (with the same login details; in theory they are linked and creating one should create the other but it practice it doesn't seem to work all the time)
• Let Clojure/core know your github username and JIRA username so they can set up the correct permissions
• Clojure/core need to create your account on build.clojure.org as well - see below

Setting up a new contrib project:

• Create a new GitHub repo (requires Clojure organization admin privileges):
  • Specify project name (must be approved by Clojure/core)
  • Specify description
  • Team: Contrib Commit
  • Add Post-Receive URL Service Hook: http://infolace.dnsalias.net:8080/github-post (for autodoc)
  • Disable Issues tab
• Create a new JIRA project (requires JIRA admin privileges):
  • Specify name (same as GitHub project name)
  • Specify key (approved by Clojure/core, derived from project name)
  • Specify project lead's JIRA account
• Setting up builds (requires Hudson admin privileges, except step 2):
  • Create Hudson user account for authors
  • Edit ci_data.clj in the build.ci repo add the new project / update authors (so they can run builds / cut releases)
  • Run build.ci Hudson job
  • Force Hudson to reload its configuration files
