Trello Board [!E] – What Does [!E] Mean in the Name of a Trello Board?

I agree with your friend about not dividing up into separate boards by type of job.

With your examples such as 'Design ideas' etc, I think they really do fit naturally within different lists on the same Board. It's exactly the sort of usage that Joel demoed in multiple videos about Trello.

The only thing I can think of, to help manage very long lists, is to use Trello's Labels system to put categories on cards, and then use filtering. You should definitely give meaningful names to the default labels.

I wrote up some tips on how to use labels recently.

Having said that, fairly early on the Trello on Trello board got huge, and eventually they reduced the scope of it. So it's does seem to be a well-known problem.

If the user is in the same organization as you and the board is part of that organization, you can automatically add them to the board:

1. Click the Add Members button and they will be listed under the current members section.
2. Click a user and select Add to board.
3. They will get added immediately, without going through the email / accept process.

There's more information about it on our blog: Improving Organizations: Adding Members and Self-Join

If they are not in the same organization, you will have to go through the normal invite process.
