What a MyForums button does, is that when you click on it, it takes you to a page with the 25 most recent threads you have posted on. So if AG gets more players with AG3, there will be more forumers. More forumers = More posts = Hard to navigate forum pages.
Then why not have a separate 'corner' of your profile show several threads you follow closely/like? You can paste those threads in that section for future use!
This would cut back on all the hassle of making a single button that would have to search for your threads...
