Information may be distributed as long as it is not obscene or libelous or does not advocate or incite imminent unlawful conduct. The sponsoring organization is encouraged, but not required, to include its name and address on the distributed information. College groups may post information on bulletin boards, kiosks and other display areas designated for that purpose, and may distribute materials throughout the open areas of campus. Noncollege groups may distribute materials only at the site designated for noncollege groups.
