Is there any way to fine-tune the permissions for board members? For example, I want to allow board members to create cards and comment on cards, but not move cards between lists or alter lists. 
Trello Fine Tuned Permissions

Trello is very much like a wallboard with Post-it note cards with lists.Anyone with physical (edit) access to the board can make changes.Currently, the best approach is to discuss the issues with your team members and set guidelines for everyone.You may not be able to enforce the guidelines, but card activity tracks who made what changes so you can tell who changed what.Visit the development boards by Trello to suggest changes.  Vote on cards for features you would like to see.
