There are different participatory instruments in Switzerland which allow citizens to put new issues on the policy agenda. The focus of the research was to classify them into three basic categories: 1) petition 2) agenda initiative and 3) citizens‘ initiative. E-collecting mechanism can depend on the specifity of used instruments (policy impact of an instrument), as well as the insitutionalisation of the instrument (new, old). Cases from e.g. Finland, Latvia, Switzerland, .. show different systems for e-collecting.
