Hey Klowy.
If you want to apply try to be a full member again, you are going to have to be much more active then last time. Because as I recall, you were voted out of trial status for inactivity and since you are saying you are grounded and such, that will most likely present a problem for you.
I would suggest that you instead apply to the 1upZ division, which has a freely open application process. It has some of the benefits of a full member, but not all. And you could always apply to be a full member at a later date.
You are still most welcome to apply for full membership now, as you have waited to required amount of days, I just don't want to see you rejected again for the same reasons as previously.
Let me know what you decide.
