I just commited the new feature to svn that allows you to give a single user edit permission on any module without creating a special role. If you need to give more than 1 user permission on a module, you should use a role. The new feature utilizes a SmartDropDown control that I implemented using Sarissa for the Ajax magic.  You can start typing a user name or email into the dropdown and the dropdown will suggest matching users from the database. You can either click or arrow down to select the user.

The feature is particularly useful if you want to give a user a blog in your site without creating a new role just for that user. It does work with any module though, not just blogs.

I will probably make another release with this feature in a day or so.

If you are using MS SQL or PostgreSQL, you will need to run the stored procedure script.
