When to post on the forum?

The Gemini DR forum is for you. If you have any question that you would ask anyone in your department or to data reduction expert in general, it could as well be posted on the DR forum. It is complementary to the HelpDesk tickets, which are better suited for questions and requests that need immediate attention, and specific technical queries which would be best addressed by an NGO member or Gemini staff.

For example, the question:

I have problems when using gfresponse. It does not seem to finish and produces the error message: Gibberish-Gibberish-Gibberish. Is it a bug or am I doing something wrong?

is more for the  HelpDesk system.

But, the question:

How do I get the best set of biases for my GMOS data?

should be submitted to the DR forum.

Note that if the forum Moderators receive the same question in HelpDesk tickets related to a given bug or a common problem, they will post it with its solution on the forum.
