+### "Choice of forum" problem
+
+Communication work like flow of water -- they start and go where it's convenient, where there is least barrier.
+Bug reports or discussion could happen in person at work, on Twitter, on Gitter chat rooms, or on GitHub issues.
+
+Maintainers, on the other hand, want specific information on specific places. For sbt:
+- Questions on [Stackoverflow][1]
+- Issue report on [GitHub Issues][2]
+- Feature and contribution discussion on [Lightbend Discuss][3]
+
+Often, we get into a meta discussion of "ok. but not this forum." Let's call this "Choice of forum" problem.
+
+Basically, by the time the problem is happening, it's counter-productive to engage in the Choice of forum discussion. (Exception may be if someone tries to contact you personally without invitation) But let's say if there's a lively discussion going on in Twitter/Gitter, the best you can do would be to gather as much as information there instead of trying to move the forum elsewhere.
+
+Once the discussion has settled, you can then gather up the info, and re-post them yourself; or ask them if they are up for reposting the information to GitHub Issues or Discuss, if you think it needs further investigation.
