Webinar & Twitter widgets
Both the Webinar & Twitter widgets are automatically activated in all accounts. Nonetheless, you can deactivate them at all times from the Admin > Interface section of your account.
The Webinar widget is to keep you informed of when the next no crm.io webinars will take place.
The Twitter widget is @noCRM's twitter page, which we recommend that you follow since it's where we post all the updates.
