Does that help I am attempting to manage my projects a little better so I am looking at attempting to apply some of (eventually all) the features of scrum.
AS A [person/role]
I NEED TO [do something]
SO THAT [provides business value].
AS A user of the XYZ application
I NEED TO get reports of ABC faster
SO THAT we can increase our conversion rates.
ACCEPTANCE CRITERIA - The database reliably completes transactions on average in 2 seconds.
AS AN administrator for the database server
I NEED TO upgrade to the latest version of FancyDB 11.7
SO THAT we can improve the average transaction time for XYZ users to 2 seconds.
ACCEPTANCE CRITERIA - the new version starts successfully, the XYZ developers sign off on the test installation of 11.7, data migration is successful, we have cut over to the new db
I wish this help you You will have to close them by hand unless you write some server plugin or notification event listener that will do this for you, as the one coming with the scrum4teamsystem template. Sorry for the bad news...
Does that help You can write user stories as tasks, cause sometimes is needed for planning a technical implementation. I dont know Taiga.io but, for example, in Attlasian Jira, you can create a US "As a user I want to send an email", which could have a subtask called "Create service for sending emails"
