There are sometimes you might need to post a note on an alien wiki than your own, for example to contact a subject which most likely notices messages at his home wiki. Though it can be difficult directly to know how to post on an other-language wiki (I know you can add a lang parameter to the URL, but that is a bit of hassle), mostly you need to know where the *button* is.
I propose in combination of SUL to enable a way to have a global interface language default setting, that will manage the transition to allow easier communication on alien wikis.
