Not a stupid question at all! I had to go find them! Okay, so I think your options are a) follow them in Mastodon if you have it, b) follow the #fotovorschlag hashtag so you see what everyone is doing each day or c) befriend a cool German and ask them what's going on! 😂 There may be a d) but I don't know about it! 😂✨

I can't see who you were replying to, but as a supercool German (🥴), I can confirm that d) "all the above" is correct 😀 The FotoVorschlag Masto account posts a new prompt every morning at 8am (German time).
