I don't use QR codes. I don't use the URLs as they are hard to read out to conference audiences. I use the number codes and you are expiring them every X days. I have to log in every X days and keep them. Why?
Because they are in slides. My presentations are all over YouTube. I wrote a book and put a Menti code in it. I can't let those expire. That would be really bad for people reading my book.
I'm a paying customer but I would pay monthly or yearly to have codes that never expire. What's the diff between letting me refresh it every 14 days and letting me pay once to not have to log in every 13 days and worry I will forget?!?! I will pay for that.
Thanks.
