can we limit the number of topics used by a user?

[Gerald Jimenez]

This may sound like a silly question but our business wants to limit the number of topics assigned to a question to a maximum of 3.  Is this possible?  ie in a similar manner that is done on this site.

Yeah, that could work.

If you already have your department field, I would put this in the workflow "create" transition as a post function. Or in a listener for catching when the reporter changes.

If you don't already have a department field, you could create a new script field.

But ultimately, here is a snippet of code for getting the list of groups for a user (assuming you already have an issue object).

ComponentAccessor.userUtil.getGroupNamesForUser(issue.reporter.name).findResults{groupName->
    if (!groupName.startsWith('department')) return null //exclude groups that don't start with department
    groupName.replaceAll('department-', '') //return just the department
}.join(', ') //in case there is more than 1
