97Mailing Lists
98-------------
99
100If you can't find what you need in these docs, try consulting the mailing
101lists.
102
103`Developer's List (llvm-dev)`__
104  This list is for people who want to be included in technical discussions of
105  LLVM. People post to this list when they have questions about writing code
106  for or using the LLVM tools. It is relatively low volume.
107
108  .. __: http://lists.llvm.org/mailman/listinfo/llvm-dev
109
110`Commits Archive (llvm-commits)`__
111  This list contains all commit messages that are made when LLVM developers
112  commit code changes to the repository. It also serves as a forum for
113  patch review (i.e. send patches here). It is useful for those who want to
114  stay on the bleeding edge of LLVM development. This list is very high
115  volume.
116
117  .. __: http://lists.llvm.org/pipermail/llvm-commits/
118
119`Bugs & Patches Archive (llvm-bugs)`__
120  This list gets emailed every time a bug is opened and closed. It is
121  higher volume than the LLVM-dev list.
122
123  .. __: http://lists.llvm.org/pipermail/llvm-bugs/
124
125`Test Results Archive (llvm-testresults)`__
126  A message is automatically sent to this list by every active nightly tester
127  when it completes.  As such, this list gets email several times each day,
128  making it a high volume list.
129
130  .. __: http://lists.llvm.org/pipermail/llvm-testresults/
131
132`LLVM Announcements List (llvm-announce)`__
133  This is a low volume list that provides important announcements regarding
134  LLVM.  It gets email about once a month.
135

138Online Sync-Ups
139---------------
140
141A number of regular calls are organized on specific topics. It should be
142expected that the range of topics will change over time. At the time of
143writing, the following sync-ups are organized:
