Expecting instant response isn't always fair. Its good to see that bestchange have solved their issue and these DT members negative tag plays the main role here. They can remove their negative trust anytime when they feel it necessary but if they didn't do that than maybe bestchange won't feel it necessary to solve the issue within short time. So i am gonna give a big amount of credit to all these DT members who took their action for a better solution.
It's better suit if you say "it's good to see Changehero has solved the issue." BestChange isn't directly involved here. In fact, BestChange had nothing to do if changehero wouldn't come with solution. But why no one talks about reputation of Changehero at all? I am sorry if I am missing anything.
Temporarily the neg was good, may be that's what forced to solve the issue. I don't know though but now that the case is closed and DT should remove the tag.
