Frontier Airlines Question

[Elmo007]

I booked a flight on Fronteir and chose my seats. I was thinking of changing my seats but nowhere on the web site did I see a place to reselect seats. I was about to call but the recorded message said there was a 27 minute wait to speak to an agent. Dis I miss a link on the web site to change seats? Its not a huge deal but I am curious.
