Do you offer a free trial
No. SideNotesIM can only be used by existing customers since it is no longer offered for sale.
However, if you downloaded SideNotesIM in December of 2020, there is a tiny window of opportunity that has allowed you to use the program for free for 20 days. We'll honor this opportunity for a limited time, so please contact us at sales (at) bluenotesoftware.com and we'll email a link to you so that you may purchase a license for your business for $199 that allows you to use SideNotesIM on all the computers on a single network (up to 100).
