Organisers hope up to 2,000 people will gather for a conference next month aimed at giving more power to older people.
The aim is to elect representatives for the new Brighton and Hove Older People's Council, thought to be the first of its kind in the country.
The nine-member council will fulfil a shadow role until the next city council elections in 2003, when a second election will take place using a proper electoral roll.
The new council will receive information from the council, ask questions and make suggestions.
It is expected to address issues affecting the lives of older people, from housing to health and community safety.
Sheila Schaffer, chairwoman of Brighton and Hove's Better Government for Older People Steering Group, said people should not expect the conference to be all about old people quietly sitting in corners discussing serious topics.
She said as well as the important debates, there would also be a lot of fun.
She added: "I think younger people will be surprised when they see what is going on. Elderly people like to try new things."
The conference is at the Brighton Centre on November 5 and 6. Admission will be free.
