thanks for your quick reply and for all the interesting variety of useful information for iWebbers and RapidWeavers. yes, i figured out that you have a swiss account. and paypal.ch also allows credit card payments. unfortunately, paypal.de has not updated to this mode yet, and there is no tiny link at all for non-paypal customers. "unfortunately" i have a german account. hope paypal changes this soon.
ok, i already found the choice for language preferences. and, if you don't want to change your profile language here at Profile=>More=>Language preference, there is still the possibility to use different languages on the buttons from within the button building application.
