I can finally edit my errors! Finally act on the errors of mine and others' errors listed in the complaints thread!
Here's what gchiaren said recently in another thread.
We just released some new tools around this! Underneath every submission you should see an "EDIT THIS SUBMISSION" button, which allows you to make edits. It's a lot more like a Wiki this way, where changes can be kept track of as submissions (hopefully) improve over time. Unfortunately, only admins can change out items while this is still in Beta... If you want to get an admin's attention in a submission's comment thread, you can always @-mention them!
We'll be working on full item edit-ability soon. There's a tool to merge duplicates but it's kind of hidden. You can report a duplicate item using here: http://equipboard.com/duplicate_items/new

EDIT: Now that I have used it, maybe there should be a checkbox in there Needs Improvement category that says something like "Miscellaneous Item", meaning an item that has no music value to the artist. Like SPAM, or iced tea.
Also, that Edit Submission button makes me nervous, hopefully people won't abuse. Probably should make a comment on the submission before you start editing.
