Hopefully this isn't a silly question, but does anyone know Spanish communities to practice talking with other learners and possibly natives?
If you are at / near a college / university, search for practice groups there!
There are apps that will help you find exchange partners. The two I've used are Tandem and Lingbe. They have some similarities.
Tandem will help you find long term partners. There are paid tutors, as well as people who will exchange for equal time.
Lingbe will connect you with a partner immediately. After the conversation, you can decided to stay in touch (or not). I've spoken to dozens of people in at least ten different countries.
