THobson - i feel your pain sir
i used to get rabid about spelling and grammatical errors, but nowadays, having mellowed somewhat, it's more a case of the occasional roll of the eyes. everyone makes mistakes from time to time, but there are those who just don't seem to care one iota...
as far as the mission making scene goes, it seems that grammar, spelling, punctuation and all that jazz, is more of an added bonus - if an author is diligent enough to take the time to check the prose, the mission could also very well be of a high standard.
having said that, with the stark lack of capital letters in my posts, i'm a fine one to talk, mmm?
