Hi Twkasun52  (nice name   btw)

When I first joined this forum, I was reading everywhere (just like you do now) "make sure to post quality comments" so this is how I tackled it.

I always try to help as best I can, I mostly hang out here in Beginners and helps forum, there are lot of users seeking help
I take the extra time to research the topic I am about to post about, if need be.
I offer links to quality content about requested topic, if I have any to share.
I look at the question/dilemma through my eyes - in other words, what reply would I like to get.
I offer my honest opinion, if my fellow is seeking it.
Politenes goes a long way, it's nice to be nice  
I never write posts with the thought of getting Merit in return.
I actually never expect anything in return, it shows in your answer (ok, Thank you is always nice).
Enjoying it, makes the whole "task" easier.

Sometimes all this could be just a couple of sentences put together, so you don't have to write any articles (to answer your question). Anyway at least I feel like this.

Sorry for my rumbling, my mind was flying to new heights there a bit  

Anyway, hope this helps, cheers.
