I love that you are working on this, and I hope you won't get frustrated! Chat is working bidirectionally now, which is awesome :)

Base informations

Minecraft version: 1.8.9

DiscordIntegration version: 3.0.2
Dynmap version: Dynmap-2.4-forge-1.8.9

Expected behavior

Messages typed into the Dynmap chat box should show up only once in the Dynmap chat history.

Actual behavior

Messages typed into the Dynmap chat box are getting echoed twice to the Dynmap chat history, once by Dynmap itself and again by the DiscordIntegration mod.

Steps to reproduce

In this screenshot, I typed "test from dynmap" into the Dynmap chat box and I see my message twice in the chat history: http://i.imgur.com/yjzcOWE.png (the name of our Discord bot is "PotatoBot")
