I grabbed a burger from an American fast food chain and swallowed it immediately, as I had not eaten for a while. I boarded the machine and could feel a slight stomachache but decided to ignore.
However, if you are able to link to us from another major site (school site, language site, maybe even a good private site), I will be able to convince my colleagues to make an exception and upload your lessons.
Thanks for the tip: We will add a lesson on colours! About the topical lessons around the home: Do you have specific words that you think should be added? It will take a while until we upload the new version.
