I completely agree with Trohde’s proposition.
Absolutely. Yes.
I previously had the same thought myself and am grateful to Trohde for raising it.
I think it’s worth remembering that OGS can be a complicated and confusing site for new users (thanks to its awesome array of options and features). The word ‘Challenge’ has a very formal and combative tone which may leave a newly challenged user feeling bullied into accepting for fear of imagined site mechanics that they don’t yet understand.
