Hello Helga,
Thank you for the suggestion! I’ll pass that along to our product team.
In the meantime, the main part of the plugin visible on your website is the sign up form itself. Within AWeber you can change the text on your form to whatever language you prefer, it’s free form. Just click “Sign Up Forms” and choose the form you’d like to edit. You can find full instructions here:

In addition, if you’re using the “allow users to sign up to my list when registering for my blog” option, you can change the promotion text as well from the plugin settings.
Those two things should make sure the parts of the plugin visible on your website are in the language your visitors are most comfortable in.
If you have any further questions or suggestions you can reply here or send us an email to [email protected] any time.
