Enjoy your one little victory in this arena WOW, you shan't have another, stick to basketball, where your marginal knowledge is at least somewaht entertaining, because when it comes to debate on this subject, you are unarmed, truly a mental midget among intellectual giants.
A contraction of shall not Lurker, pity you could not even get that right. A less than 2 line sentence with punctuation and you call it a run on? What do they teach you boys down in Texas?
I was taught that you put a comma between the statement and the name of the person being addressed (shall not, Lurker). 
Also I was taught that the length of the sentence doesn't determine whether it is a run-on sentence or not. Rather it is the number of phrases and their relation to each other as well as the continuity of thought transmitted. As it appears that you are trying to slap down another poster, comment on their marginal basketball knowledge and berate their ability to debate; I would say that your statement contained too many different topics for one sentence.
Actually, all topics within the scope of the sentence were germane to one another relative to the subject matter, so comma's and semi-colon's were really all that was necessary for the flow and continuity of the sentence to be correctly structured. However, I could have used a semi-colon rather than a comma between "another" and "stick", as it is a hard pause to introduce another point within the scope of the sentence. I also misspelled somewhat, I can't believe you missed it.
As far as "shan't" being akin to "ain't", I could not disagree more, "shan't" is a legitimate contraction of 2 words, "ain't" is no such thing, it is an abhorrent non-word used by common people who choose to continue mired in the commonplace, therefore, your point holds no value. Your describing it as a colloquialism carries more weight, only in that in the lost art of the English language, such a beautifully artistic contraction has fallen into disuse on this side of the pond, it is not the case conversely. It is however, hardly an incorrect contraction, it is completely proper.
You do have me dead to rights on neglecting to place a comma between the statement and the proper name addressee, I stand humbled before your discerning eye.
Thank you for the compliments. I have enjoyed our discussion even though Ko**, La****, Sp***, Ma** and other topics were not involved.
On the use of shan't, I discussed this with my wife and a few friends. They agree with you that it is a proper contraction which has fallen into disuse. So either I remember incorrectly from 40+ years ago (VERY LIKELY) or I had a teacher who had their own predjudice (I like this excuse).
And we probably will have to agree to disagree about the run-on sentence. I would have probably used two sentences as such, including the use of the semicolon as you pointed out.
"Enjoy your one little victory in this arena WOW, you shan't have another; stick to basketball where your marginal knowledge is at least somewaht (sic) entertaining. Because when it comes to debate on this subject, you are unarmed, truly a mental midget among intellectual giants."
Thanks for the thought provoking exchange. It was fun.
