Hi Noel and welcome to the community.
Hello. I am Lacey. I'm just joining to learn some things & an needed a place to ask questions.
Welcome! You have come to the right place!
Hi, I'm Zhaoyang Wang, welcome to @royalwzy
good place to getting start with oracle community.
1.Me in 3: I have dragged 3 badges from my earned badges, but they will disappear when the page refresh;
2.Welcome Abord Badge:I thought I have completed "The Oracle Community Welcome Mission", I have voted on 2 ideas, createded an idea, and joined the "Getting Started" social group, but the progress stay on 73%;
3.Wound you mind telling me what should I do if I want to apply for moderator in Oracle Community;
Hi, welcome to the forum.
1) this is a known bug and week fixed with the next major software update
2) there are more than the three parts you mention to earn this badge. To check what's missing go to your reputation tab and click lower right corner the mission. On the flip side of each mission you see which tasks to finish. You have to scroll down to see them all.
3) you don't apply for moderator. You first stick around the forum, build yourself a reputation, become known to the other members and finally the admins will contact you if they looking for a new moderator.
Thanks for your patience, and you clearly solved my problem 1 & 3;
On the "Welcome Abord Badge" issue, I need to add some content: I believe that I have completed all the parts of this badge, but those 3 parts don't work;
Right now the whole point and badge system seems be of order (see No points earned for Correct/Helpful posts in the past two days).
This may be the problem, but we have to wait for an admin to tell us what's going on.
