Memrise does not care what you think! If they did then they would personally respond to your complaints! It’s all about the bottom line, and the bottom line is always about money. Are you making Memrise money? Maybe not, but indirectly, as a course creator you are.
I just wished that people who are paying to use this site would band together and refuse to pay (it would only take a month). Then, maybe Memrise would listen to the many concerns raised by their deletion of individual course forums.
I have seen many posts by individuals perplexed as to why they (Memrise) would take this invaluable asset away.
Be heard. Stop paying until they (Memrise) listen.
