For users or categories/events you frequently refer to, you can create favourite lists.
Log in and click My profile in the grey navigation bar.
Your Dashboard opens.
Click Settings.
Click Favourites on the menu to the left.
Use the Add Indico user button to identify persons to add to your Favourite Users list.
To view your Favourite Categories, you first have to mark them as such from within the category itself using the bookmark feature (see screenshot below). Any categories you mark as a favourite will be displayed under Favourite Categories.
