A group, E-Nemeton and Nemeton are all different things with different intentions.

1. A "group" is something that every NOD member can create on the website, in order to have a discussion group with people all interested in one particular subject. These groups are thus informal discussion groups.

2. An E-Nemeton can be an online (discussion) group or community, but which is actually external to NOD. The name "E-Nemeton" therefore actually relates to an online affiliation.

3. A Nemeton is a local group which extends its activities beyond only the internet, but also holds local meetings, rituals, etc... and is affiliated with NOD. A varation to this is the Vernemeton, a more loosely affiliated local group.
