This is a 'work in progress' post that I hope to add to as I gather information about national portals for crowdsourcing / citizen science / citizen history and other forms of voluntary digital / online participation.
While portals like SciStarter, Crowds4U and platforms like Zooniverse, FromThePage, HistoryPin etc are a great way to search across projects for something that matches your interests, I'm interested in the growth of national portals or indexes to projects (they might also be called 'project finders'). It's not so much the sites themselves that interest me as the underlying networks of regional communities of practice, national or regional infrastructure and other signs of national support that they might variously reflect or help create. If you're interested in specific projects outside the UK-US/English-language bubble, check out Crowdsourcing the world's heritage. I've also shared a 2015 list of 'participatory digital heritage sites' that includes many crowdsourcing sites.
If you know of a national portal or umbrella organisation for crowdsourcing, please drop me a line! Last updated: Feb 7, 2023.

This post was inspired by the apparently coordinated approach in France. The Archives nationales participatives site has 'Projets collaboratifs de transcriptions, annotations et indexations' – that is, participatory national archives with collaborative transcription, annotation and indexing projects.
They also have Le réseau Particip-Arc, a 'network of actors committed to participatory science in the fields of culture', supported by the Ministry of Culture and coordinated by the National Museum of Natural History.
EU-citizen.science is a 'platform for sharing citizen science projects, resources, tools, training and much more'.

David Haskiya reports: 'medborgarforskning.se/ Provides an intro to citizen science, a catalogue of Swedish projects, etc. Seems to be part of an EU-network of such sites. Summary in English here https://medborgarforskning.se/eng/'
A Swedish national hub for everyone interested in citizen science (medborgarforskning). The project was funded by Vinnova – Sweden’s innovation agency, the University of Gothenburg, the Swedish University of Agricultural Sciences, Umeå University.
gov.uk lists some volunteering portals but they don't make it easy to find online-only opportunities.
https://app.unv.org/ lists online and on-site (i.e. in-person) opportunities around the world, although some of them might stretch the definition of 'voluntary roles'.
