Right now it doesn't seem to allow you to add a certain skill outside of what is searchable in a database. My personal example is not being able to add "Unreal Engine" or "Archviz/Architectural Previz". There is an option for "Unity" so other game engines should be considered as well.
Suggestions: keep expanding skill database, be able to add any skill manually or suggest skills to be added that are then approved to the skill database.
