I miserably lost the fight against your ticket system! No way to modify anything as guest user and no way to create/register a new user as described in the Jitterbug help pages. Could you please tell me how I can modify an issue or where I can find a description how to proceed?

You can only add new messages to tickets, mainly by a simple follow-up e-mail preserving the e-mail subject.

From my understanding this is also the accepted way to add an IPR notice after initial submission.
