Glitches in Chat

[xehu]

In a small number of cases, I'm getting reports about users experiencing difficulties with entering the text into the chat due to a combination of glitches and UI issues. Manifestations I've heard of include:

• [Glitch] The 'enter' key not working (i.e, it doesn't send the text into the chat);
• [Glitch] When entered, the chat shows up as blank (and does not appear, either to the user themselves or to their teammates).
• [UI] Some users don't seen an obvious 'send'/'enter' button, and type materials without sending them into the chat.
• [UI] The character limit is not clear, and users who type too much run up against the character limit, which sometimes causes the chat to glitch.
