Hello!
I see from a change you made that was reverted that you removed a redlink on one of the trope pages. This isn't an issue, and we don't have anything written down about it one way or the other - it's a style thing that helps set us apart from TV Tropes.
Some of the Tropers here see redlinks as invitations to create the work pages that they're trying to link to... and a majority of the mods who have expressed a preference are in that camp. You won't get in trouble for disagreeing with a mod here - we specifically say that in our list of how we do bans at ATT - but it might lead to edit wars if people decide to be stubborn.
No worries either way, as long as everybody agrees to disagree on it.
