Hey everyone! I just joined and I'm wondering what I''m supposed to do with all these flowers I'm finding?

You can either sell them in your shop or lay them at the survival memorial statue here

There is an achievement set for laying flowers at the statue. The highest tier (1,500 flowers laid) will get you a forum title 'Got Laid', which can then be equipped and shown when you post around the forums.

what the Forum Titles look like is not knowable until you get them or until you go to the Subeta Wikia and look them up. The Got Laid one reads "username got laid" where in your case you'd see TheBellJar instead of username.

Many Forum Titles have text that shows up on your HA that is similar to their Title, but not all of them do. Some of them you'd think they'd go above your name but they don't, and others are the other way around.
