When you create an advertiser you pick a name to identify it. After a while, however you may decide that the name is not as useful as it could be. Perhaps another advertiser with a similar name is causing confusion, or maybe there was simply a typo in the original creation. advertiserEdit allows you to change the name of an advertiser.
The advertiser website created in the previous part is now using multiple subdomains. It is simple enough to create new advertisers for each subdomain, but it would be nice to keep the stats from the original advertiser aganist whatever subdomain they were shown as. We want to rename that advertiser to use the full domain.
Note, if you refer to an advertiser by name when making overlay requests and then change the name, new overlays will not be allocated against that advertiser. For this reason we recomment that the advertiserID parameter is passed to overlay requests instead.
