You may notice that prior to receiving your reply accusing me of posting under several names and of being American I corrected the typo on the title of your post "Training cente goons and their level of communication". I didn't make a fuss about the mistake at the time as it would have been a rather petty thing to do. However, as the resident expert on such things perhaps you can clarify whether my spelling of the word (after i corrected your mistake) as centre is generally considered to be British or American English?
