 +====== New Rotation Settings ======
 +
 +Most options are self-explanatory but some of them should be explained a bit more
 +
 +===== Alt out =====
 +
 +You can use external trade script (ETS).
 +
 +First of all, ETS should somehow count incoming hits. Usually it's done by including something like 
 +<? include('/path_to_another_script/in.php') ?> into your templates.
 +
 +Then each click has to go through SCJ out.php so SCJ can count clicks at thumbs, and the scj_out.php redirects to ETS_out.php and ETS_out.php decides where to send a click: gallery or trade. You have to specify ETS out.php in Rotation - Settings - Alt Out like /url__to_ETS/ETS_out.php?url={URL}
 +
 +So usually it looks like this:
 +
 +/scj/out.php?url=http://gallery.html -> SCJ counts clicks at thumbs and redirects to /url_to_ETS/ETS_out.php?url=http://gallery.html
 +
 +As you can notice {URL} is being replaced by an actual gallery URL.
 +
 +**Alt out and custom galleries**
 +
 +Let's say we have an URL like http://domain/gallery/gallery_slug/index.html and this is a custom gallery. W\o rewrites it looks like scj/out.php?url=content&slug=gallery_slug - so if SCJ decides to send to a trader - it redirects right away. Otherwise it can load 'gallery_slug' from DB and show a gallery.
 +
 +When we use ETS and user clicks at http://domain/gallery/gallery_slug/index.html this click is being sent to scj/out.php?url=content&slug=gallery_slug, SCJ counts hits and redirects to /url_to_ETS/ETS_out.php?url=http://domain/gallery/gallery_slug/index.html and let's say ETS_out.php decides to send to a gallery (http://domain/gallery/gallery_slug/index.html). As you can see at this point we ran into an infinite redirect.
 +
 +**So what to do**
 +
 +By default you use alt out we add &ao  to gallery's URL and SCJ redirects to ETS_out.php?url=http://domain/gallery/gallery_slug/index.html**?ao**
 +
 +In this case when ETS_out.php redirects back to SCJ we know that we have to show a gallery, not redirect to ETS_out.php
 +
 +===== Category Boost \ Separate Thumb CTR =====
 +
 +By default gallery's CTR is the same for all categories but there's a way to have a separate CTR for each category
 +
 +Rotation Settings -  Boost gallery CTR in category, % 
 +
 +This way each thumb gets CTR for each category and total CTR at the same time. For example, a thumb got showed 10 times, with 1 click at index page,  2 clicks in category A and 3 in category B.
 +
 +so total CTR = (1+2+3)/10 = 0.6
 +
 +with Category Boost = 50 (50%), 
 +
 +For category A (1+2***1.5**+3)/10 = 0.7
 +
 +For category B (1+2+3***1.5**)/10 = 0.75
 +
 +
 +
 +=====  Wilson Interval for Rating =====
 +
 +This is a better way to sort galleries based on rating (votes). Let's say we have 2 galleries: id 1 has 10 votes (9 likes and 1 dislike) , ie appove rating is 90% , while another has just 1 positive vote so approve is 100%. But we are are more confident that id 1 is better then id 2 because it have 10 votes, while id 2 may have just one random accidental vote. So we can place id 1 higher even thou id 2 has 100% approval rate. It is called Wilson score confidence interval.
 +
 +The downside here is that if you want to output rating next to the gallery it'll look like it sort is wrong.
