Collecting small things in the Wiki

Hi documentation members,

I'm looking for a place to collect little tips and explanations, for example "Why results the formula -2^3 in 9?" or "Calc calcutates wrong! 9.87€ + 6.54€ results in 16.42€."

And also a place for HowTos, which are not a FAQ and which are to small for a guide, but might be useful. For example an explanation, how to get the coefficients of an interpolation polynomial.

It should be outside of your documentation workflow and needs to be easily edited, but have a basic predefined structure.

Kind regards
Regina
