It's funny... we have people here from Europe, Turkey and other locations that sing in their native tongue with no (or few) complaints.  Nowhere here do I see any indications that this is an English only forum.  I don't see Mr. Robertson complaining to others that use English as their second language, and trying to correct them.  He wasn't complaining about the song, anyway, but the fact that Tony didn't use the past tense of the verb "fix" in the post prior to his.  Therefor, his attack seemed personal and not general in nature.
 
Those of you who frequent the Sonar X series forum are probably well aware that a number of posters (some with post counts in the tens of thousands) don't use grammar correctly all the time.  Many native born English speakers commonly don't know the difference between the words to and too.  Some don't know the difference between adverbs and adjectives (i.e. good and well).  And, some don't realize that there's no word "alot" in the English language (it's two words-a lot).  But Tony wasn't coming here for grammar lessons, he was here for advice on his music.
 
This is about as close to a TOS violation as I've seen in a long time.  A little tolerance would go a long way, and if Mr. R really tests out in the mid 130's, like he claims, he'll understand this (btw, the mid 130's is still 10 to 15 points below Mensa level).  Peace.
