Required taxonomy field dilemma!

I have designed a drupal site where there are 'teacher' roles. The users with teacher roles can create blogs as well as forum post. The standard authenticated user role can only create forum posts.

To keep track of what the teacher role users are doing, I have set up taxonomy terms using the names of the users(teacher roles) and I have them set as required fields when they publish content to the site. So the teacher role users will have to select a required taxonomy field when they publish blogs or forum posts. To hide the required field from the forum post for the standard authenticated user roles I have used the 'taxonomy_role module' to do this.

Everything works flawlessly and the taxonomy is keeping track of all content to its relevant user.

Now the owner of the site (administrator) wants to publish forum posts created by authenticated user roles to the front page. Basically, if he sees a good forum topic created by an authenticated user, he would like to be able to publish it to the front page.

The problem is that the required taxonomy field kicks in and wants the administrator to select a required taxonomy field even though the administrator has not been selected for this role and is not even present on the list!
Is there a way I can override the required taxonomy field for the administrator? I don't want to include the administrator in the taxonomy terms user list as this is going to mess up views pages that I've created based on the taxonomy terms.
The easiest option I can see is to change this taxonomy field to not required. I don't want to do this either as the teacher roles are more than likely to forget to select the taxonomy term if they don't have to select it and this content will not be gathered on views pages that are dependent on the taxonomy user name terms.

Need to get this sorted. Very grateful for any help.

Thanks in advance.
