Exchanging of sticky notes between users (who are spread across the globe) happens over the cloud. To create a new contact, you are first required to create a new sync account from Notezilla.
Select a sticky note in Notezilla, right-click on its title/toolbar and choose 'Send To / Contact' from the menu. The following 'Contacts' window will be displayed.To add/edit contacts, click on the 'Manage Contacts' button.
Now, click on the 'Add Contact' button and proceed with the steps shown to you.
An email is sent to your contact, requesting him for the approval. Once approved, you can then proceed to send sticky notes to the contact. If your contact had already added you to his contacts list & you had already approved him, then the approval step is skipped.
If any other user has already added all the required contacts, then you can quickly fetch the contacts list from his account.
Notezilla also allows you to import multiple contacts at once from a file. Press the drop down arrow next to the 'Add Contact' button to import contacts from a file.
