I think some abilities/features depend on your style, At 1k points you can make meme comments, I think that is for everyone. For me I could use custom templates for meme comments at 6k and got my third submission at 18k. If/when you get three submissions (subs), you have to use 0, 2 or 3 subs each day to keep 3. If you make 1 sub on a day, you will go down to two. It will stay at two until you make two subs, then it will return to 3. Here's a meme about how many points you get for various activities

Secret memes can mean different things to different users. I'll have to come back for that topic.
