E-petitioner
E-petitioner is an online petition system developed in Scotland, characterised by its integration into the processes of representative democracy. It allows citizens to raise and sign a petition, read background information on the issue, and add comments to an online forum associated with each petition.
The system evolved from a research project conducted jointly by the Scottish Parliament, the International Teledemocracy Centre at Edinburgh Napier University and BT Scotland, as part of an investigation into the use of information and communication technologies in encouraging democratic participation.
It has been used by national governments, local authorities and a students union.
