I wasn't suggesting they code their own site up. I only mentioned my involvement to suggest I had some familiarity.

I've been at these events where attendees are actively asking people for assistance. My nightmare fuel was people actively seeking out the photog during the event for that assistance. Asking the photog to be tech support for this is not something that should be on their list of duties. The photog could possibly provide suggestions for the couple to use, and put the burden on them.
