After some discussion with @BjornPehrson_47a0 and @Jaran_Eriksen, I thought it would be a good idea to have a sample topic that shows how to interact with groups.
There are several communities of practice (COP's) which we've defined here as "groups" in Discourse. If you're part of a community of practice , you can ask to be added to a group. These groups are sometimes related to proejcts (such as WIMEA, MURIA, or the Sci-GaIA project itself). Some COP's are not related to projects, however, such as the AfricaGrid Pharmacology Science Gateway - so they don't get a category, but only a group.
If you want to inform everyone in a group of an issue or topic, simply use the group name :
and so on.
Be considerate, however, since by naming people directly, they will be notified directly (via email).
Finally, if you need to know what groups you belong to, you can see this in your profile page.
