Scoreboard and chat. I gave the username "redstonelasher2010" admin privileges (so, it's not filtered for you). It only lets whitelisted words, and numbers up to 1000, be entered. Non-whitelisted words and words with punctuation appear as "###". Clicking enter when asked what you want to chat exits the chat. I will publish this stuff and more in a project in a few days. Tell me if anything is wrong with it.
Most of the wordlist is by @Griffpatch
