Can someone tell me what the ?action= thing is at the end of a url... not what it is just what i could search for so i can find some tutorials to get more knowledge of it.
I already know some stuff i just need to refresh my memory and learn how to use them effectively and stuff.
(?action= was an example).
So if anybody could tell me a keyword to search or link me to a few tutorials or something, that would be great.
