Wonderful tips.. grammar is essentially the make or break part of your post. No matter how important the message is but if there are grammatical mistakes in it, it is totally unappealing to look at..

I would like to add here that most users tend to use difficult words in their posts in order to grab the audience.. i would strongly advise against it. Use common words instead so that your message / post is understandable for everyone on the platform..

Excellent tips over all.. all thanks to @techslut..
