Adding extra words just to make your post longer may not be better idea compared to the one liner that gives complete information. Long posts do not always mean quality post and short posts are not always low quality post. Having said that I always strive to give my best when posting on forums.This is true, however, we strongly encourage users to create longer meaningful posts that have a decent discussion in them. Short posts may sometimes fall under poor quality and may be deleted. As long as the posts are of good quality, then you have no worries.
