Uploading your talks ahead of time is quite straightforward, and it helps the tea and biscuits arrive on time!
Step 1: If you don't have an Indico account, register for one here and then tell me about it so that I can associate your talk with it. Those that already have an Indico account should be able to skip this step (i.e. I should have found you on their system, but there's no 100% guarantee that I found the "right" you). If you're having trouble with the remaining steps after doing this, I'll do what I can to help.
Step 2: Log in to Indico.
Step 3: Navigate to the agenda and select the session your talk occurs in.
Step 4: Select your talk.
Step 5: Select the "Add Material" option.
Step 6: Upload your talk.
Step 7: Relax and have a biscuit.
