[image] The 6th participant was annoymous which disappeared when a member post. I am wondering if I can increase this number and if this is expected behavior.

I think you get up to 5 users. For example: author of the first post, 3 frequent posters, author of the last post author of the first and last post, 4 frequent posters author of the first post, author of the solution, 2 frequent posters, author of the last post or similar combinations. If the author of the first post is also the author of the last post there is the frame around their avatar

Is this on a PM in the header or this? If it’s the 1st, I believe the logic is here: frontend/discourse/app/components/header/topic/info.gjs main get maxExtraItems() { return this.args.topicInfo.tags?.length > 0 ? 5 : 10; } frontend/discourse/app/components/header/topic/info.gjs main get participants() { const participants = [ ...this.args.topicInfo.details.allowed_users, ...this.args.topicInfo.details.allowed_groups, ]; return participants.slice(0, this.maxExtraItems); }

this is just in the topic list , I gave up on customizing the header participants. These replies are part of Discourse with no modification. [image]

This list is about the topic’s featured users. I’m not sure if you can modify it. Perhaps you could, programmatically.

/* Reduce spacing between avatars */ td.posters.topic-list-data a { margin-right: 2px !important; /* Reduce gap between avatars */ display: inline-block; } /* Remove any padding inside the cell */ td.posters.topic-list-data { white-space: nowrap !important; padding-left: 4px !important; padding-right: 4px !important; } /* Ensure avatars don't have extra spacing */ td.posters.topic-list-data .avatar { margin: 0 !important; } td.posters.topic-list-data, th.topic-list-data.posters { min-width: 175px !important; width: 175px !important; } This fixed the wrapping issue, where the avatars were stacking on top of each other.

you can modify it by css to target a single poster, latest or op, etc.. for example, you can do: to hide OP: @if $this_setting == "false" { td.posters a:first-child .avatar { display: none; } } for latest poster if they are the OP and not the only poster: … .posters { a:first-child .avatar.latest:not(.single) { …} }

For what it’s worth, since you don’t seem to have a deep knowledge of CSS or programming (I apologize if you do!), I’d recommend keeping the customizations few and simple. Only do what you feel is necessary. Each additional customization is a potential point of failure in the future. I’ve gone down this path before, and regretted some modifications I made to my instances.

It would be nice to switch this to max 8 participants since for some reason it wants to wrap double lined like this. I tried fixing this wrap but it affects my other areas that have thumbnail/blog view. [image]

the only thing I am doing to the mobile view is removing things that are overlapping or taking up too much space like Group titles or flair.
