I have to admit I have never used this feature so far. But now other users have me thinking more about it.
What is it for, exactly? I mean is it most useful for comments? Something else?
Is it because comments roll down off the front page?
If I have this disabled, will SER still re-post to the same domain, different URL?
Does SER keep track of what's been posted and not post the same content again?
Do "post first article w/o links" & "link only on x % of all posted articles" work ONLY with articles or any type of post?
