I'm an admin for a small Trello board used to organize action items for a development project, and we've been using member assignment to 'track' all relevant parties to the card's topic. I.E. if Bob is working on a bugfix for code that Jim wrote, both Bob and Jim are added as members to the card.
The trouble with this scenario is that adding a member to a card will automatically set the "Subscribed" flag, meaning that Jim will receive notification e-mails for the card. This is normally fine, but our project manager in particular is wanting to only receive e-mails regarding specific action items she needs to do, not every single card she's involved in (e.g. a "Meet with PM" task that Bob sets up).
Is there some way to add a member to a card without subscribing them? While subscription and assignment are two separate things, they are set at once and I can't remove subscriptions admin-side. Since it's a bit unreasonable to ask folks to log in and manually unsubscribe themselves from the things they don't want to see, the closest solution is for the PM to change her notification setting to "Never," which of course means that no e-mails will go through at all. That's troublesome for a whole other reason, namely that we're trying to show her that Trello is the way to go and without the task e-mails she'll likely forget to check it. ;)
Apologies for the wordiness. I can't find a setting or a good answer via Google so I figured I'd explain the "why?" behind the situation before the questions are raised. This may be a "Don't do that" in regards to how we're assigning members, but I figured it's worth an ask regardless.
