Migrate to Discourse from Basecamp 3

I’ve seen it’s possible to migrate to Discourse from selected other forum software. Is there support (or a plugin) for importing messages from a Basecamp 3 project?

NB: I know it’s possible to export a Basecamp 3 project to HTML.

There isn’t currently an importer. It’s not immediately clear (in two minutes looking from my phone) how to get the data from Basecamp. An html dump is a worst case option. I could have missed something, but you may need to pull it from the API.

I’ve written several importers. If you have a budget, you can post in #marketplace or contact me. See https://www.literatecomputing.com/discourse-migration/ for some general notes on migrations.
