Adding extra levels
Adding extra levels

Have added the following levels to the Node form:

    network, learning, network_learning

As the tags are used for classes, they can't have spaces or odd characters.
Consqeuently also changed the form to have a label - value form, rather
than just values. This works with existing editions (tested with Seoul).
