Language mutates, often in unfortunate ways. "Login" is not actually a verb if you follow the "rules" of English. You log in. "Log" is the verb. As much as it bugs me, though, I've learned to accept misuses becoming the norm; this is hardly the first time a word has evolved from butchery. There used to be a billboard in SF on which a gym advertised that you could "workout in your pajamas!" I've learned to grimace inwardly about that, "alot", "alright", and other "violations". Because -- as in the case of "alright", we already have ... "already".
