<p>I know it means "person who made the thread" but I only see it used here. Other forums usually just say "thread starter" or something. It's just so annoying when you don't know an acronym stands for.</p>
<p>Original poster, or just original post</p>

for all abbreviations</p>
<p>ooh thanks!</p>
<p>Original post sounds better. Poster sounds like something you stick on a wall.</p>
<p>It kinda depends on wheter you are using OP as the object of the sentence, I think. "The OP was saying in their post that..... makes it "original poster", .. whereas "in the OP the statement was made..." makes it "original post". Ok, I have too much time on my hands.... splitting hairs here....</p>
