When creating a schedule for your solicitation, you can set reminders for important upcoming dates. By doing so, you will receive email notifications about these upcoming events (ex. Q&A deadline for questions, deadline for responses to questions, end of offer-phase, etc.).
To set a reminder, go to "Schedule" and click on the icon behind the date you want to set a reminder for. A popup window will appear where you can select the date and time you would like to be notified.
If you are the Lead Buyer in the solicitation, you can also set reminders for your colleagues. To do so first click the 'manage' link behind the date you want to assign colleagues to, and add 'Responsible Persons'. For each responsible person, you can set individual reminders by clicking the same icon again.
