I subscribe to a few channels with upwards of 300 active users at any time, and with all the "guestN"s out there, the rename notifications tend to ruin the actual chat. I would prefer if you could disable name-change notifications for channels like you can disable join/leave notifications. It would be even cooler if you could specifically turn off when stuff happens to a user named "guest", as those are likely initial things that won't change as often afterward.

In addition, level change notifications do just as much harm in chats where most users are automatically promoted to manager. While this can help a channel to always stay online, it also helps to fill the chat completely and make it almost unreadable.

Thank you.
