There is no fee to do this. If an insurance company declares a vehicle non-repairable, it must apply for a non-repairable certificate and submit the vehicles's salvage certificate or title within 15 days of payment of a claim. The insurer must also notify the DMV if an owner keeps a non-repairable vehicle.
Recommended Maximum Number of Users in a Group. For Windows 2000 Active Directory environments, the recommended maximum number of members in a group is 5,000. This recommendation is based on the number of concurrent atomic changes that can be committed in a single database transaction.
For groups, samAccountName length is an interesting corner. It can be 256 characters, however, if you try to create a group name with that length via ADUC, it'll limit you to only 64 characters. This is because the CN max length is 64 characters, and ADUC sets the CN and samAccountName values to the same.
