I'm not a user of Alcumus by any means, so I honestly don't have loads of information to add on articles. (Unless they involve how to do something such as: Algebra, Trig, pre-cal physics whatev etc. or can be easily researched upon)
This being said I would love to help in any way I could. Being very active on a different wiki, don't be afraid to ask questions involving 'how to' contribute to articles, or anything else.
I'll put up some examples of basic things on my profile incase it gives any ideas of something you may like to add.
So ugh.. yeah, not sureeee what else to put here.
