I think the Sandbox lacks a feature. I don't know what you guys do think about it but I came to think that many posts of the Sandbox get "forgotten" really fast. Even if there are activities on it. And because they are "answers" to a "question", there is no possibility of upping with a bounty or something.
Even tnb people, which are really helpful, can't fully validate what you're doing in the sandbox, since they have things to do too - obviously.
So what do you think is doable? Or what should we do to "up" a post, since updating or working on it does not do the job? I don't want to flood chats or something, that's why I'm asking it more broadly here.
