You did nothing wrong and nothing offensive. The bad attitude you're experiencing from
@cgw here has been an ongoing problem with no real solution, for years. He's just allowed to continue bullying folks like this all over the site. I can't even make new threads here anymore without feeling anxious that it's going to attract the negative attention of cgw.
Don't let cgw ruin your TPF experience or stop you from sharing your work though, despite how persistently he tries ruining other people's experiences on this site. Even if I still have anxiety about posting here because of him, I still do it. You can't let him ruin it for you. Considering how long this has been going on unchecked, he's just going to keep bullying people here either way.
