Oddly, I do have a "Your Answer" box here despite the protection (I'm not answering since I don't have a better answer). So it only seems to pertain to the main askubuntu, not the meta. I do not think it is evident "on this site" does not include the association bonus (it says "You've earned a bonus of 100 reputation because we trust you on other sites in the network", and the only reputation number ever displayed in the site header, etc. includes association). See also meta.stackexchange.com/questions/210481/…

This is a UX fail, to have multiple flavors of reputation that aren't evident. If nothing else the message should state "posting an answer now requires 10 reputation on this site (and the association bonus doesn't count)." But really, if the site is going to grant 100 reputation for association bonus, it should be the same as other rep so there aren't mixed messages ("We trust you because you gave good answers elsewhere! Except we don't trust you quite yet.")
