I am pretty new to Q2A but I want to make a plugin where users can put tags on their answers and then the answers for a question can be sorted by tags and the cumulative scores of answers with the same tags get calculated and shown.
I have no idea what type of module/plugin that has to be.
P.S. I've been sniffing around the database. I found a table called qa_posttags which should be able to contain the tags for answers given. Answers, questions and comments are all types of posts so it should be able to work out somehow.
Now I need to find a way to overwrite the answer form to add a field for tags and after that a way to display them.
