First of all, I hope you're all fine with this whole pandemic thing going on. To be honest, can't remember the last time when I went to a hunting party with my friends. I've never used this app you are talking about because I've never needed to since one of my friends deals with the arrangements, so the only thing I have to do is to show up and enjoy the process. Usually, we hire sound equipment & event lighting and throw a party afterward to celebrate being together and spend some quality time having a nice meal and listening to music.
