'''Sharealike''' is a required reintegration clause of several [[parametric license]]s in [[Creative Commons]] and some monolithic ones like [[GFDL]]. It simply means that anyone improving a work must share the improved work with others who wish to use or improve it. It is a key feature of the [[GPL]] too which applies this principle to [[source code]]. ''however see [[problems with free software and open source models]].''

The [[Creative Commons by-sa]] license is quite close to the [[GFDL]] but is incompatible with it. Things licensed under the CC regime are not part of the [[GFDL Corpus]].

[[Trolls]] like sharing, but bite you on the leg if you try to tell them they have to share with you, even if you are doing harm to them.
