BookCrossing/BookCrossing Localization

What about turning "MembersPlus" into something more BookCrossing-ish such as "BookCrossingPlus" or "BcPlus"? Or something common in all the languages, so that it keeps its name? Any other suggestion?

Oh no! "Members plus" is sacked anyway, as far as I know.
We happily returned to the term "Wings"! (Didn't we?)

Yes, it's Wings again. No more Members Plus.

I didn't know that. And when I found MembersPlus on the translation, I simply translated it. That was the reason for my question. I shall find it now and change it. But you must be aware that in the English_USA version there are several places where it says "MembersPlus" :-D
