Well, I'm trying this mod as it's designed for ZC150.
I found it owesome :) Special thanks to brandonturpin.
If I'm correct (to be confirmed by brandonturpin), the pop up 'Share This Page" is designed purposely to shows only the "numberring" in a glace. To do the tweet, just click on the tweet button "follow @.." (right below FB button).
Btw, I also have doubt on the "appId=162410943835993" on subscribe_sidebox.php, I've tried to change the appID to my own appID, but it makes no different.
Besides that, the <div id="fb-root"></div> is duplicated, one with appId, and another nope. I tried to remove the second one, it makes no different as well. Guess the above two doubts are just for experimental purpose on not live website.
Lastly, should I follow the msg "<!-- Place this tag in the <head> of your document -->" ? It's not stated at readme file. However, I tried to paste it before the <head> of html_header.php and it makes no different too.

Thanks, more ppl try it on, hopefully, and share the result with us.
