With federal stimulus money coming to an end and the state budget strained, nonprofit organizations are searching for sources of future revenue. A state-sponsored conference scheduled for next month and geared specifically to that topic is already almost sold out. The Governor's Grants Office is holding is its first grants conference since 2008, on Sept. 12 at the Inn and Conference Center at University of Maryland University Center, in Adelphi, Md. Seating capacity for "a day of intensive workshops" is 710 and "we're three-fourths full," said Susan Casey, spokesperson for the grants office. Casey said the grants conference is being held by popular request. "A lot of people asked for [it] in light of the fact that it's a whole new climate in the grants world." The grants office helps state agencies, local governments and nonprofits find, win and manage grants. The grants office also passes along federal funding to the state to the appropriate nonprofits.
