Hello and welcome to the herd!
FiM lives forever in our hearts. The candles are still burning bright, so bright that G5 ponies need to wear sunglasses.
There's no G5, it's FiM2.
Alright, alright, I changed it to say "My Little Pony" in general. These questions should be popping out when creating a topic here, and we were actually planning to change it to say MLP, but things kinda broke there with one of the forum software updates.
Until these fields start working again and show during topic creation, in the meanwhile one may or may not choose to copy&paste these into their intro topic, so you're welcomed to modify these questions, add your own, or in general add anything you'd like to say about yourself. It doesn't say these questions are required, and given the feature responsible for asking these is down, we won't blame users for not including these in their topics.
Looks like you've got confused while taking your first steps in general, sorry about that.
There is indeed that welcome popup for new accounts, that disappears once you do take these first steps, and new accounts need to have their first posts approved, it's just a measure to filter obvious spam. (Posting topics in certain areas might still require approval)
That said, everything should be nice now, and if not, I encourage you to share your thoughts in the Feedback forum, ask questions/report problems in Site Questions, or just poke ME or other staffers if you'd like to ask anything.
