Grammar errors to be fixed

Every now an then I find a Memrise error. For example, “de behoefdte” wants me to respond “a need.” De means “the,” Een means “a.” It is beneficial to learn the gender of a noun, making me suspect that the speaker was tired and misspoke. In addition to remembering Dutch vocabulary, I have to also remember those words where Memrise is wrong. Can these kinds of errors be reported and fixed?

Find the course forum and report the mistake(s) there.
The thread title will look like this:

or something similar, perhaps the language that the course teaches is included
