Thank you Miguel for starting this hashtag and thanks Chris and Brandon for the inputs.

This discussion seems the right place to kick start the Group on Correspondence tables. 

I have just created a new directory on GitHub for the work of this sub-group. The link to this discussion is mentioned in the Readme file.

I am currently working on the deliverable I listed under "Before the Hackathon". You will see the updates in the folder soon.

Suggestions and contributions are as always very welcome :)
