If I understand correctly, you want to create an English wiki and quiz in Malta and link them together.
To do this, you need to add the interlanguage prefixes for "en" and "mt" in the interwiki table. Here is a description of it:

You should probably remove links from all other languages ββfrom articles. Otherwise, they will appear as trash at the bottom of a large number of articles.
PS: It's great to hear that you work with the Maltese language! I love it:)
