By the end of the day, I gave up on learningsite, since it seems to only allow students in if the administrator has issued user names and passwords, and since the best solution it could come up with for having Previous and Next buttons on the first and last pages (respectively) was to bring up a screen saying "You are on the first [or last] page." Absolutely silly. It's no error of the user's that there's a previous or next button where there shouldn't be.
So I'm diving deeper and have downloaded MySQL and PHP and will attempt to set up my own login system that allows any user to come to the course, register with a user name and password of choice, and get in. All nicely automated. The course is going to be free and open to anyone, so I want as little maintenance effort on my part as possible.
I have one week to turn something in for my class, so I'm thinking I'm insane for going this route. But if I stick to my basic interface ideals, I'll have a better product that will be nice advertising for what I can do, even though I may earn some nice gray hairs and make co-workers and friends think I've been possessed by a very irritable demon for a week.
If you've got solutions for my main two complaints there, please let me know!
Thank you!
