Hi, and welcome to the forum.
Symbol sets are stored in
The OpenOffice User Profile at user/registry/data/org/openoffice/Office/Math.xcu. Other students could
replace their symbol sets by copying your Math.xcu to their profiles. I don't see a method to
merge your changes into their symbol sets unless they (carefully) use a text editor. You could presumably write a program, say in
Perl, to merge these text files. Anyone making direct changes to the user profile should make appropriate backups of the files first.
If this answered your question please go to your first post use the Edit button and add [Solved] to the start of the title. You can select the green checkmark icon at the same time.
