Will this help with my situation? I currently have two different instances of wordpress powering ajhenderson.com and danihenderson.com. I recently picked up hendersonfamilies.com and would like to be able to have a network of blogs based in hendersonfamilies.com that will link to and aggregate posts from ajhenderson.com, danihenderson.com and any posts made by other blogs that might actually be based out of hendersonfamilies.com. I am familiar with how to migrate the ajhenderson and danihenderson.com instance in to a MS configuration, but need to be able to maintain ajhenderson.com and danihenderson.com as the primary domains for those blogs while still allowing the aggregation on hendersonfamilies.com to occur.
Is the domain mapping plugin the best way to do this or is there some other way that would be cleaner and easier? Also, can this setup be made to work with buddypress?
