Like other people, bad grammer and spelling tick me off. I can understand when its just a one off here and there, but when its every post and all, then I get really annoyed. I have a tendacy of spelling things wrong, and sometimes accidently putting in a letter or two that shouldn't be there on small quick replies, which are honestly by accident, but i will correct them if i see them in time. I rp alot, and for things such as text chat, its a big no-no. I normally can't read anything in text chat, appart from a few words, but i will addmit, in casual talk, i will use brb and b, or when in a rush g2g. Apart from that, thats about all I use.
