I don't believe it will be. Since this works off of the information stored in the w3t_Posts table which has been changed for 6.2 it will probably break this mod. I haven't seen the code for 3.0 and can't remember if Max went with a table join between the events table and the posts table to grab the information. If so this will also be a problem since .threads 6.2 uses a table join between the Users table and the Posts table and adding an additional table will most likely impact speed. (without a lot of work in streamlining things)
