As the voice of the computing research community, CRA is actively developing a proposal to the NSF CISE solicitation

Computing Community Consortium (CCC): Defining the Large-Scale Infrastructure Needs of the Computing Research Community
http://www.nsf.gov/pubs/2006/nsf06551/nsf06551.htm

While it is not feasible to develop a proposal via a committee consisting of all CRA members, we intend that all CRA members will ultimately be involved in this activity unless they specifically decline to participate. We are interested in your ideas on how best to: catalyze long-term research visions for computer and information science and engineering (the NSF CISE disciplinary fields) and engage with funders after visions have been formulated to best impact funding emphases.

We welcome your ideas and expressions of interest and support; please contact ccc@cra.org
