[Change access list to group access]

I have a very simple passwall script that changes a prim state to phantom for avatars on an approved list within the script. For the sake of simplicity, and because the list can become VERY lengthy, I would like to be able to change the access list of avatar names to a single group UUID. Being a complete novice at scripting, I have no idea what alterations to make to the script in order to achieve this.

Here is the script:

// access_list is the list of every person you wish to be able to trigger the wall phasing out

list access_list = ["name1", "name2","name3"];

// phase_length is the length of time in seconds to hold phantom state

float phase_length = 1.0;

default

{

     state_entry()

     {

         // Set status to not phantom on start just in case it got stuck as phantom

         llSetStatus(STATUS_PHANTOM, FALSE);

     }

        collision(integer num_detected)

     {

         // check to see if the person who bumped into the wall is on the access list

         if(llListFindList(access_list, (list)llDetectedName(0)) != -1)

         {

             // if the above is true, then phase out the wall to allow passage by applying a phantom state to the prim

             llSetStatus(STATUS_PHANTOM, TRUE);

             // set the timer to activate phase_length (set at the top of the script) seconds later

             llSetTimerEvent(phase_length);

         }

     }

         timer()

     {

         // when the timer goes off, the wall is made solid again by removing the phantom state

.         llSetStatus(STATUS_PHANTOM, FALSE);

     }

 }

[what happens during a sim restart?]

I really just need clrification on a technical point. What exactly happens during a private region restart? I have heard some talk as if it is just a simple power cycling of a server, and I have heard others describe it as if the sim is moved to another server entirely. Are private regions placed on different servers during either a standard maintenance restart or during an owner initiated restart? Thanks.

[Uneditable terrain]

There is a small irregularly shaped strip of terrain on my private estate that cannot be edited. Terrain editing tools have no effect. How can I get this fixed?
