We currently have 2 tags, "safecracker" and "channel-form" which I think should be made a synonym as people who've only recently come across ExpressionEngine will probably know the feature as Channel Forms, but there's over 250 questions under the previous name of Safecracker they may otherwise not find.
I concur and have added this tag synonym to the system. Thank you for suggesting this!
Agree with the synonym though currently the tag is displayed as safecracker. Since Channel Form is the name going forward, shouldn't this be the one that is displayed?
