You should definitely join the academy..especially if time is your biggest concern. If needed you can always put a note in your profile that you are limited on time and would prefer to request tasks when you have more time to perform. One of the nice things there is that you can be assigned tasks or you can ask for permission to perform certain tasks. You are not obligated to accept any that you are not comfortable with or don't have time for. You may also negotiate with the TMs if you need more time or something changed... I love itDefinitely encourage you to try it...and if you dont' like it, then just take yourself out
