I have an 11th hour request (aren't they always) for a basic captive portal for a conference. The conference organisers want a basic captive portal with changing images and a username and password field. I have created this as a web login with the galleria skin. So far no issues.
The part I am not 100% on (and this could just be me over thinking this) is how to have a single account (username and password) that allows all conference attendees to simultaneously login. I believe the conference organisers want to have the username and password either written on whiteboards or including in their conference introduction Powerpoint.
