So this actually happened a long time ago I just never complained about it until now:

I was a beta user of SO and originally my account was located at: http://stackoverflow.com/users/871/andrew-g-johnson -- I used Google to login as soon as it was available

Then when you guys rolled out Facebook Connect and I clicked that.  Suddenly my account id was changed: http://stackoverflow.com/users/428190/andrew-g-johnson.

I liked my low user id and beta badge -- is it possible to get those back?


Question: xeCJK and paragraph indentation
Answer: In the log file you find this warning:

*************************************************
* xeCJK warning: "option-invalid"
* 
* The `indentfirst' option only can be set in the optional argument to the
* \usepackage command when xeCJK is being loaded.
* 
* Please do not set it via the \xeCJKsetup command.
*************************************************


which is self-explanatory: do

\usepackage[indentfirst=false]{xeCJK}


Be warned that languages loaded with Polyglossia may revert the setting (Italian, for instance).
