ok I just noticed that the closed accounts bugs have happened from January, it wears off after a day. for other members, I just see the “challenge” and green mark on their picture, yesterday I was able to challenge the closed accounts because it didn’t take 24 hours since they closed
I’ve got a strange bug for the new “online challenge” feature.

Ok I'm confused navigating I have a bug issue and maybe a sujestion or two where do I go to post is it right here?

Depends on what it is. If you have a bug about the website, not the apps, you should look to see if it's been reported before and if not, you can create your own topic about it. If it has, you can add to that existing topic.

I found out that you can even challenge members that had closed their accounts. for example @Pushingthatwood and you can challenge members that weren’t online for a day (for example, @JDcannon) so, I need to click their username (which gives them 1view) to see if they are online or offline
