Recommendations for online groups and courses to improve speaking skills?

Hi everyone,

I’m an introverted person looking to improve my speaking skills, especially for interviews, social interactions, and public speaking in general. Nervousness often holds me back, and I’d love to build more confidence.

Are there any online groups or communities where I can practice or get feedback? Also, if you’ve taken any online courses that were truly helpful, I’d appreciate your recommendations!

Thanks in advance for your suggestions!
