another way I make sure I only post what I want to get posted is by writing my post in my computers writing program first or in my email account first as a draft. then I take some time away from that post for a bit and come back to it a bit later, reread it, if its still what I want to post then I send it in.

all computers come with an operating system (most if not all are now on windows 10) to find your writing program with windows 10 click the little windows icon at the bottom of your computer screen then in the pop up window that tell you whats on your computer look for the words microsoft word 10, if you dont see it right away look in your windows accessories folder in the same pop up window.

then you just write your post, save it (you can save to computer or make a folder for what you want to save on your computer.)

to write a post as draft in email account go to your email account log in, then write your post like you would any other email with one difference do not fill in the send to box. it will get saved to your emails "draft" box.
