You don't have to send the Notezilla sticky note to others with same log in detail.
Since all the devices are sharing the same login, the sticky notes will get automatically synced. So you will automatically see the sticky note appear in your PC and your iPad too.
Watch this short video to find out how this works:
Go to your PC, right click on Notezilla
icon and choose Sync option. There you must have "Sync automatically" option enabled. Once you create a note on one PC you should see it on the other PC within a couple of minutes.
