Hey nostr:npub12vkcxr0luzwp8e673v29eqjhrr7p9vqq8asav85swaepclllj09sylpugg nostr:npub1getal6ykt05fsz5nqu4uld09nfj3y3qxmv8crys4aeut53unfvlqr80nfm ! Totally new here, and I've been struggling to "do" anything since I created my account a few months ago (specifically, I can't follow anyone and I'm not even sure messages work). Would you have any troubleshooting advice ?
