Anyway... clearly, there is no disagreement here. Over 90% of the readership of lj_userdoc agrees with me that the verb, "to log in", should be spelt with a space, while the noun is a single word ("login").
Now, I'll reveal what motivated me to post this. There is this Zilla bug:
In a comment to this, Brad said,
log in -> login (for consistency with other parts of the site)
In order to resolve these inconsistencies, or the "wrong" consistency, I would like to ask everybody to take a look around the site for a while and report all occurrances of the wrong "login" vs. "log in" to me. I will collect all of your reports, list all the relevant translation codes, and then give a bundled report to lj_english where they will hopefully change it.
I've already harvested the most obvious place, the (ahem) "login" page, so you don't need to report that :)
Thanks for all your help.
