Restrict the technologies used in a language-independent question
If you want to create your own question in language-independent but restrict the technologies used by your candidates (which can be useful if you want to use the same exercise in different types of campaigns), follow those steps:
1. Create your own question in Language Independent following this tutorial. "Language Independent" may be found at the end of the list.
2. Go back to the campaigns screen and create a new one including Language Independent in the technologies' list, alone or among others interesting you for this campaign. This option only appears if you created custom questions by selecting it.
3. When hovering over your question or block, click on the grey pencil edition icon and then on "All Languages" and select your programming language-s.
You just have to save and invite your candidates!
