I am making this for those of you who don't know what a productive post exactly is, so, I made these examples:
Non-Productive post:
Topic: K-mod, my PC won't fit in the case, by Trekkie. (all names are used as an example)
Responding to: Doom; "Well, you could cut the balloon down where it doesn't fit."
Your post:
well that doesn't work 4 me so how mutch baloons did u have 2 cut. so Don't do this trekkie.
--------------------------------
Productive post:
Same topic and message to reply to.
Your Post:
I see... Could you tell me how many layers of balloons do I have to cut off? Thanks Doom. Try this Trekkie.
-------------------------
So, which one do you want to write?
EDIT: Forgot something.
