I was unable to find the previous time, but reproducing things wasn't that hard. Create a new .user file, open it up in a text editor, and paste in this between the "document signature" and "/document" elements.

Now, what controls the spells which show here is the <list> expression in the oSplBkTb2 portal. I used your Studied summoner file and filled in the default for that class above. If you want to expand it for future classes you'll be appending to the Classes.??? and Spellbook.??? sections in that tag expression.

For example, if you wanted to add a class called "Taxman" with a Classes tag of "Classes.Taxman" and a unique ID of the class helper of "cHelpTax", you would change this:

((hero#Classes.StuSu_v1 & Spellbook.cHelpMMT) | Spellbook.PrayerBook | Spellbook.MeditaBook)

to this:

((hero#Classes.Taxman & Spellbook.cHelpTax) | (hero#Classes.StuSu_v1 & Spellbook.cHelpMMT) | Spellbook.PrayerBook | Spellbook.MeditaBook)

Hope that helps!
