Hmmm, since it’s every 4 days it really isn’t such a big deal is it? If you can’t remember and want to reset, just open sTalk and talk to him. He tells you it’s too soon if you try to do it and it hasn’t been 4 days. Worst case scenario you need to check 4 times (and that would only be if you actually didn’t remember that you reset your character the day before and needed to check on day 1!)

Easy reminder – send yourself a tubmail when you reset. It’ll be stamped with the time and date.
