244 <li>The <a href="http://lists.cs.uiuc.edu/mailman/listinfo/llvm-announce">
245 LLVM Announcements List</a>: This is a low volume list that provides important
246 announcements regarding LLVM. It gets email about once a month.</li>
248 <li>The <a href="http://lists.cs.uiuc.edu/mailman/listinfo/llvmdev">Developer's
249 List</a>: This list is for people who want to be included in technical
250 discussions of LLVM. People post to this list when they have questions about
251 writing code for or using the LLVM tools. It is relatively low volume.</li>
253 <li>The <a href="http://lists.cs.uiuc.edu/pipermail/llvmbugs/">Bugs &
254 Patches Archive</a>: This list gets emailed every time a bug is opened and
255 closed, and when people submit patches to be included in LLVM. It is higher
256 volume than the LLVMdev list.</li>
258 <li>The <a href="http://lists.cs.uiuc.edu/pipermail/llvm-commits/">Commits
259 Archive</a>: This list contains all commit messages that are made when LLVM
260 developers commit code changes to the repository. It is useful for those who
261 want to stay on the bleeding edge of LLVM development. This list is very high
264 <li>The <a href="http://lists.cs.uiuc.edu/pipermail/llvm-testresults/">
265 Test Results Archive</a>: A message is automatically sent to this list by every
266 active nightly tester when it completes. As such, this list gets email several
267 times each day, making it a high volume list.</li>
