It is fairly simple to setup Notezilla to send and receive Windows sticky notes over local network.
Install Notezilla on all the computers where you wish to send and receive notes. Add computers in each others's list as per the format. When you add computers to Notezilla , Windows firewall will automatically ask you if you want to allow Notezilla to communicate. Note that when adding computers, Windows Firewall should be enabled. Only then it will detect and add Notezilla . Follow the above steps on recipient computer as well so that the firewall settings are updated.
Create a sticky note and choose "Send To->Computer" from the left top button and select the recipient and click on 'Send Now' button to send note to another computer.
You will receive a notification on bottom right. If you want the sticky note to directly appear on other computer's desktop, go to Notezilla Preferences on both computers, click on Advanced button and select 'Stick incoming notes directly to Windows desktop' and press OK.
