Updating a Plugin for Vanilla 2.3
About 6 years ago, I made a DiceRoller plugin for Vanilla 2.0 or 2.1... I don't remember which version. The username was different (ToastyFish), but I can't get logged back into that.
Anyway, I've had a user ask if I can get it updated for 2.3 and I'd like to be a good open source community member, but I'm having trouble figuring out where to start.
The original plugin extended CommentModel_BeforeSaveComment_Handler. Is there a event or method or whatever that I should be overriding for Vanilla 2.3 so I can intercept and modify the text that the user typed in (to turn something like 1d20 into a number between 1 and 20)?
