styling forum

Hi All,

I had a screenshot ready to go but it looks like you can’t attach so I will do my best at explaining what it is I am trying (and failing) to do.
I have created a child theme for bbpress in my theme folder already and have been working in the loop-single-topic folder but no dice. What I am working on is this:

Here is my site’s forum

1. Change the title of Freshness to “Started By”
2. remove all of the data in the new “Started By” column. I want to replace it with the next section. Right now it is the last person to reply and how long ago the recent reply was. I do not want either of those.
3. Remove bbp-topic-meta from the “topic” column and place just the “bbp-topic-started-by” under the new “Started By” column.

And for the love, can anyone tell me what that red bar above the forum is? I saw that it was a warning that was supposed to phase out after the last update but I am 100% updated and still seeing it.

I really appreciate any help!
