The "Notify Me" tab allows you to set notification for each individual wiki page. You can check to recieve updates on edits to the page or discussion posts or both. This would allow you to customize notifications to recieve them only on topics of interest to you.

You will be able to customize notifications to only recieve them for particular topics, or you can set notifications for the entire wiki here.This link will allow you to recieve notifications for changes to the entire wiki, not just a specific page. In addition to monitoring discussions and page edits, you can also monitor uploaded files from this page.

To change notification preferences, click on the "My account" link at the very top right of the page header. From there, click on the "Settings" tab and scroll down below your account and profile information to "settings." From here, you can control who can use wikispaces to send you a private message (the Allow Private Messages From box). You can also use the "Email monitored changes" box below that to change your email preferences for changes to the wiki. You can select to recieve an email each time there is a change, to recieve a single daily digest email about the changes made that day, or to not recieve email notifications.
