The Expo organizer selected a dozen ideas to make the event better from people who had already visited the site.

One idea was to let people make reservations by mobile phone to more pavilions.

Another was to let people collect Expo passport stamps at less popular pavilions in exchange for reservation tickets at popular attractions. The organizer said that both ideas were good and were being considered.

Other ideas included giving a label to each visitor for them to stick onto the clothes of volunteers as an award. Volunteers could then be given an award from the organizer based on the number of labels they receive.

Another visitor suggested letting visitors sweep the ground in waiting areas while they queue so that they could experience what it's like to be a volunteer. The organizer though that this was a good idea.

Cai Guoping, who wrote a letter to the organizer about SMS reservations, also suggested the organizer send short messages about pavilion queue times and weather forecasts to all visitors at the site.

Song Laixin, a senior official of the Visitors Service Center, said the organizer believed the suggestions could make the Expo run more smoothly and that they would try to carry out all the suggestions selected yesterday.

He said they would contact China Mobile to build a short message reservation system for more pavilions to help reduce waiting times.

People can already send a SMS to the Finland Pavilion to make a reservation. After sending a short message, visitors will receive a code on their mobile phone that a machine recognizes at the pavilion's entrance. The service has been well-received by visitors.

Some Expo Clubs might be set up around the city for people to exchange their Expo experiences and what they had learned from the event.

Visitors can dial 962288, the Expo hotline, to give suggestions to the Expo organizer. Both English and Chinese services are available.
