As of now, username capitalization preferences are lost when using the @user@ variable in Deepbot. Because usernames are proper nouns they should at the very least begin with a capital letter and read poorly otherwise.
Yay grammar!
Attached is an example of my username capitalization being preserved in Nightbot, but ignored in DeepBot.
Thanks,
