Like millions of others i have difficulties spelling. I have dyslexia, and it takes me about 4 mins to type a message this long. now try and participate in a chat room with a 4 minute spelling lag. it's impossible. a spell check would cut that in half or 3/4. for us who struggle if we can get a part of the word right spell check will get us the rest of the way. Please find a way to implement a spell check it would be a massive improvement.
