Hi Konstantin,

Thanks for the super fast reply! I tried responding to your reply, but AppSumo limits the reply length.

I may be able to work around the payment issue by using a third-party tool and manually adding users to Kopnstantly. It’s not ideal, but if the features are worth it, I’ll consider it. Your willingness to add the head-to-footer script is a big plus—it would’ve been a deal-breaker otherwise.

Just two quick questions:
1. On Tier 4, does the 500-user limit mean 500 registered students total, or 500 concurrent users? I think I know the answer but want to be sure.
2. You’ve been on AppSumo before, but I’m surprised there aren’t any in-depth review videos on YouTube. The ones I’ve seen look like low-effort promos. A few honest, balanced reviews would really help your sales.

Thanks again—still seriously considering it!
