When on the Library Help webpage, click on the LibChat tab at the top of the screen. This will take you to a list of libchat transcripts.
Once you have found the transcript you would like to create into a ticket, you select the little 'ticket' icon on the right hand side of the transcript (which will flash up 'make a ticket from this transcript')
A box will then appear on the screen in which you can fill in your ticket details. Once you have finished, click on the create a ticket link and your transcript will then be transferred into a ticket and will appear at the top of the dashboard.
