In only the most literal sense has the author answered that user's question… but consider for a moment, the larger philosophy of why you have a Stack Exchange site—
Does it improve the Internet as a whole?
No. A list of links does little more than add another barrier between the folks searching and the information they seek. The primary use case of this site is search. After you've helped that one user, there will be hundreds (perhaps thousands) of people looking for that information. This site isn't really about one-on-one customer service and helping that one user. It's about creating a canon of the best possible answers for those who come after. That's the whole point.
I'm not saying that you should reproduce the entire content of the SmugMug web pages in this Q&A. But consider how you can provide a better answer to that question than simply saying "yes, I have your information. Go find it here." Perhaps a statement about how social networking fits into the SmugMug ecosystem. Perhaps a helpful summary about the various options so they don't HAVE to read a set of disparate links to figure out what they are looking for.
Creating a simple index to the answers already contained on SmugMug isn't making this site or SmugMug any better. Think about how you can provide the best possible answer; where other folks will try and do the same and the best overall information will rise to the top. A list of links does not do that.
