I am a huge fan of GigaSign and I have expressed this to Chris Wade wade@adobe.com. Now I am encouraging myself to use Send In Bulk. My huge disappointment is, Send In Bulk does NOT have a Recipient Group feature like GigaSign. So I guess I have no choice but to continue with GigaSign. The only downside of GigaSign is that it is a JAR file, so I have to use a Windows machine​ or our VMWare as I am a Mac user. Please can you add Recipient Group AND Parallel Signing in Send In Bulk... Send In Bulk should match GigaSign​'s capability.
