Sorry for the broken link in my previous post. I wanted to link to section "2.4 Provide feedback for others" in the http://docs.moodle.org/en/Moodle.org_forums_Code_of_Conduct, but it jumps to "# 3.4 Code of conduct violations"! I've already reported it in the "Documentation" forum http://moodle.org/mod/forum/discuss.php?d=195445&parent=852369.
Anyway, the same conten is available in the introduction to this forum (Hardware and Performance):
In order to help the helpers and others that may encounter the same problem:
* rate the posts useful to you (a drop-down menu appears below each post once you are logged in). This is preferred over "thank you" and "+1" posts.
* once you could solve the problem, summarize solution by replying to the thread, providing links to the documentation, discussions or tracker issues that helped you. Tag that post by adding [Solved] to the subject line.
