How to add fields - cannot find userTags

[mikejazz]

Hello!

I was looking to follow the instructions about UserTags here:
http://minimserver.com/userguide.html#Sorting album lists

But I cannot find "userTags" property in the Settings...
Could you help?

I am interested in adding a few fields that I use for classical. I manage these fields with JRMC.
Examples:
- Style - a sub category for Genre. Examples: "Concerto", "Opera and Vocal", "Recital", "Sonata", "Symphonies" and others..
- Period - "Baroque", "Classical", "Romantic", and such..

1) Is it possible to use these fields?
They are not user-defined, they are standard in JRMC
2) Is it also possible to use new custom fields?

A possible problem about Style field. In JRMC we can store a big string of text. For Classical I will make sure I have only one style, but for Other genres like jazz, I can have several. Sonny Rollins's "Night in Tunisia" has the following Style content: "Bop; Hard Bop; Jazz Instrument; Saxophone Jazz".
So, one long string with no multiple values, like in the Artist field.
How is MinimServer dealing with this?

Thanks!
