I think name is not problem but I agree that AnotherAlt does not have enough activities and posts.
He had enough posts to rank up to become a full member, but he just needed to wait a while for his activity points to renew 14 points in 14 days to reach 120 points to rank up. Currently he has only 98 activity points and that should make him wait for the next 2 periods (14x2=28 days) to fulfill the required number of activity requirements, but I must say that he only needs to post at least 1 in 14 days each period.
★ If your post count eclipses your activity by 14 or more then you will only need to make one post in the new period to get the full 14 activity. For instance, your post count is 200 but your activity is only 28. To get another 14 activity you will only need to make one post in the new period and you will then have a total of 42 activity.
