A different tech solution for this …
Dear Case Study adventurers: we’re doing a similar mapping exercise earthquake-response initiatives in the Future Makers Nepal project and decided to go for a different tech solution. Every tool for its job, and wikis are just not a good tool for structured and comfortable data collection.
So I looked for a very simple, web-based database solution and found obvibase.com, which is like Google Docs real-time editing but for databases, which Google does not provide. To demonstrate, I created the structure and first record of your database here. (To edit and contribute, use this link; it gives read-write access after a login with a Google account. Not too great to share this publicly as there might be spammers, but Google accounts are probably just as good a spam protection as Edgeryders accounts, so … .) To get an integration with edgeryders.eu, it may be possible to embed the published read-only version linked above, or else to copy results via CSV exports into a table daily.
You may also consider to duplicate this database to a new, non-public one and use that, sharing the link only with the engagement managers in these countries. Otherwise, you can’t legally collect personally identifiable information about contact persons for these initiatives. (That’s why we use a non-public database atm.) You still can publish the public columns of the dataset daily by exporting as CSV, converting to a HTML table and copy&paste’ing it into a post here.
