Set rule so that only admins can add members to a specific card
Asked by Jorge ?lvarez:

Hi Trello community,  

I am trying to accomplish something fairly simple at first glance. In our  
workspace, there are several members in our team collaborating on the board.  
I am the 'admin' and all other members have 'member' permission.   

I am looking to do the following: only I can add or remove members from  
cards, so nobody else in the team can edit the members assigned to a  
specific card.  

Thank you very much in advance for your help.

Welcome to the community :) for the moment, Trello doesn't offer much customization around user-level permissions; board members have the ability to edit most elements on a board and it's not currently possible to remove the ability to edit a specific card field.   

One workaround could be to use [butler automation](https://support.atlassian.com/trello/docs/butler-overview/) to revert changes that users make to card members.   

E.g. a command that triggers when a member is removed from a card:  

```
when someone is removed from a card by anyone except me, add member @{matchedusername} to the card
```

<br />

and another command that triggers when a member is added to a card:  

```
when someone is added to a card by anyone except me, remove member @{matchedusername} from the card
```

<br />

<br />

You may also want to add another action to alert the user, e.g. "and post comment "@{username} FYI you don't have the ability to remove members from cards!""

body: Hello Hannah,

Thank you so much for the detailed response. Your answer makes a lot of sense and I think will work for us.

However, when trying to implement them, I don't seem to be able to get them to work - what am I doing wrong here?

Maybe now it's correctly uploaded.

Thank you in advance.![unnamed.png](https://community.atlassian.com/t5/image/serverpage/image-id/216692i9225B189BE8EFAD9/image-size/large?v=v2&px=999 "unnamed.png")

body: [@Jorge ?lvarez](/t5/user/viewprofilepage/user-id/4996493) looks like you've used the wrong trigger - it should be "when someone is removed" not "when @someone is removed". The latter will be trying to find a user called "@someone".
