BiG Grid supports over 35 user communities from a variety of different research fields, and you may already be well connected to one of these. If so, your community coordinator ('VO manager') can help you get access to BiG Grid and you don't need to apply for resources yourself.
If you have no such link with one of the communities listed, please visit Getting Involved to see how you can get started with BiG Grid.
For registration in most communities you will need an electronic identity, your 'passport' to the Grid - also known as a digital certificate. You can get your digital identity from the DutchGrid Certification Authority; and if you already have a certificate from a CA accredited by the IGTF, you can just use your existing identity.
When your certificate in installed in your browser, you can enroll in one or more communities or virtual organisations. To apply for enrollment into a community, press the

Besides this list of virtual organisations that are active in the Netherlands, there are many European communities as well as listed in the CIC portal. Any other Dutch virtual organisation that might be missing can be found here (only accessible with a valid certificate).
