i made my FriendRewind account 2 days ago, i like this site because it is a good alternative for spacehey since they have more fun features, however, i'm did not like how they did the group section. it makes little since for a site that replicates the old myspace to have group chats that work like discord servers (even with the same layout.) Not sure if the OG myspace had this, but on spacehey the group chats you can post forums and bulletins, for me, this is better than having a group chan because you can archive and organize many different things, e.g: on a harry potter fan club, there are forums to discuss about the movies, others for fan creations, even one for fan theories. I know that you could do something like this on a group chat (like discord) by creating different channels based on their use, but because they're also used for texting, it is harder to archive and the more people text, the more stuff gets disorganized and lost.
if anyone who worked on this site sees this, i hope my critique will help you to improve the site a bit.
