First, congrats on coming back from a short break from work, in a time when you thought you still had a lot of active members in your box, that helped me a lot. , people still try to answer the questions in the box, even though they get a few GP. Your statement is so good to us, I've been thinking about it, for a long time. Well, I just want to say the last word, wish you all success in your work, wish the English box and the entire hoc24 community to grow and have many new recruits.
-I wish you a good day :D
