Welcome! I hope you enjoy basel as much as I do!
Have you come with one of the big pharma companies? If your/spouses work offer settlement programs I recommend you take them - I learnt valuable tram/shopping/tax back skills by doing these courses.
I did an intensive course with Inlingua which was useful to learn basics very quickly. I should do another course but I haven't got around to it yet. If you're already learning there are great resources such as language cafes which will help you use the skills you're learning.
I see your profile says you're interested in keeping fit, if you're interested in yoga send me a message - I have a friend who is a yoga teacher and I started recently. I love it and have been recommending it to everyone I meet
it's a community based program so no pressure to pay loads of fees or be amazing at it.
