The Participant Portal  has become the European Commission's single authoritative website for the publication of FP7 calls. The FP7 call-related information is no longer published on CORDIS.

This implies a general re-organisation of the web-presence, which will be implemented
gradually throughout 2012 and 2013. Key web services for the 7th Framework Programme
are going to be redistributed between the three main portals in the following way:

• Research on Europa: publishes general information on the EU research policy, initiatives
  and specific programmes and addresses the interested broad public.
• Participant Portal: is used for interactions with the participants of EU-funded research
  and innovation projects; it also provides information on funding opportunities.
• CORDIS: disseminates information on the EU-funded research projects, their
  outcomes and their exploitation.
