A bit of Discourse terminology

The ISGW Forum uses the Discourse software to create an Internet forum.


“Categories” are the primary division used to organize discussion topics. On the ISGW Forum there are several categories:

  • Site Documentation and Feedback
  • Latent Genetic Modeling
  • Measured Genetic Analyses
  • Phenotypes and Measurement
  • ISG Workshop 2022
  • R

Front page of the forum.


“Topics” or “threads” are messages posted to start a discussion or ask a question.

A list of topics.


“Replies” are messages posted in response to a topic. Most interaction with the forum will be through posting replies to existing topics.

Choosing the category for a new topic

Under each category on the front page is a brief description of the category. You are most likely to receive useful responses to questions if they are asked in the appropriate category.

Questions, comments, and discussion about general behavioral genetics topics should go in the appropriate category of Latent Genetic Modeling, Measured Genetic Analyses, or Phenotype and Measurement.

Questions, comments, and discussion related to the 2022 ISG Workshop, such as where to find files, slides, and practicals, should be posted in the appropriate day subcategory under the ISG Workshop 2022 main category.

Questions and comments about the forum itself should go in the Site Documentation and Feedback category.

Sometimes this is not entirely clear. For example, should a question about OpenMx be placed in the Latent Genetic Modeling category, or in the R category? Pick the category you think is best; a topic can always be moved by a moderator.

Starting a new topic

Navigate to the appropriate category for your new topic.

Click the “+ New Topic” button.

Click the “+ New Topic” button to start a new thread.

That will bring up the editing panel. Enter your title into the appropriate field, and then your message into the large text field.

The first time you create a topic, a message may appear next to the editing field. Once the message is dismissed, a rendered view of your message will be shown on the right.

Once you are satisfied with your message, click the “+ Create Topic” button to post your message as a new topic.

Replying to an existing topic

There are two options for entering replies.

Selecting the bottom “↰ Reply” button, which is blue in the default theme, you will reply to the first post in the topic, and the original creator of the topic will be notified that there is a reply.

Selecting the “↰ Reply” button immediately below another message, black in the default theme, will reply to that particular message. The author of that message, as well as the creator of the topic will be notified of your message.

There are two ways of replying.

Making your messages pretty

Discourse supports Markdown as a syntax for creating messages that are more than just plain text.

A quick reference for Markdown is available online.

A post on the ISGW Forum shows how to use Markdown to post blocks of code, including syntax highlighting.

The ISGW Forum supports MathJax to post complex mathematical text. MathJax uses a syntax very similar to . A post on the ISGW Forum gives a brief introduction to the syntax.

The ISGW Forum also supports the graphviz language to create diagrams. A post on the ISGW Forum gives an example of using graphviz to create a simple ACE model path diagram.
