I am preparing an email to the discord community newsletter next week with a final reminder to export projects.
This should also be interesting for people here: I built an exporter service that will export everything (This is not importing into a specific service or anything locking a user in, just giving them zip they can use) including the things missing from the default pivotal tracker export and also uses json so is less of a pain to parse.
Please let me know anything missing from the export so i can verify it is included and works (so far i have, attachments, follower ids, full project history)
