I often tell people here that challenging me on spelling or grammar here is likely to earn you a scornful response with more than a hint of ridicule. We're not writing legalese here and we can afford to be casual, and we all overlook others' errors most of the time. However, there was nothing wrong with my use of "thus." There was everything wrong with your spelling of "sentence" in a post that purported to chide me. There's the rub. Leave it off with me and I'll leave it off with you, innit.
