The answer is NO and I will give you a nice explanation to why I will not shorten them.
My posts almost always contains different topics put into one post. Simply, I could just as easily make 2 - 4 smaller messages posts because they are different or I can put them all into one large post.
In fact, I use to do the above until someone recommended I put them all in one big post. I prefer to do the latter now. For example, this post is much smaller and only deals with one topic that's specific to you. Yet, had you discussed 2 - 3 different things...you most likely would have gotten a much longer reply from me. Simply, to get a smaller message...you should only talk about one topic.
To compromise with you, I will ensure all my replies to you are small and only deals with one topic even when you talk about several different topics.
