The registration for the WAN-IFRA 2009 World Newspaper Congress - World Editors Forum began at noon Monday.
To ease registration traffic, conference badges were sent to the hotels of participants if their hotel was known, Poland native, Anna Kwawczyk, information director, said.
Participants register at the actual conference if their hotel was unknown, she said.
"Some important people registered yesterday," Kwawcyzk said. "We asked other people to register today for convenience."
There have been no major problems with registration so far, she said. There have been some misspellings of names and people have been indentified with the wrong countries on badges, but nothing major.
"There are always problems, mistakes happen," she said.
Registration will be open from Monday to Thursday.
