3rd Level Wildcards no longer supported?

In the previous version of ReCAPTCHA we could register a domain like: *.domain.com now it says that it is invalid when I try to register one.I have a wordpress Multisite network that creates domains like: site1.mydomain.com and we have tons of these sites and new ones added all the time, so it's going to become cumbersome if we have to register a key for each and every site.Any idea if there is a way around this? -- You received this message because you are subscribed to the Google Groups "reCAPTCHA" group.
