I've made the changes that we discussed in https://forum.mylittlewordland.com/d/19-synonyms-separator: Synonyms must now be separated by a semicolon ; instead of a comma ,

For example, you should use hot;spicy instead of hot,spicy.

There were two reasons for this change:

It makes it so that synonyms can include sentences with commas. For example, Hi, how are you?;Hello, how are you?
Memrise courses used semicolons to separate synonyms, so now Memrise courses should work on My Little Word Land without any changes being needed 🙂

If this broke a course that you made, my apologies, and please post a link to the course so that I can fix it! 🙂
