[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 aut…

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 dow…

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.
