Had already managed cache (but good reminder) so tried different browser (Firefox). NOW I have an error message that they detected that I've either tried multiple times to set up an account or am using a proxy (whatever that means!). So have NO clue what to do now. I made it as far as setting up an account, but somehow the account from today and the "forum" account are not "linked." So have to actually sign out from one and into another from here on out??
Regardless ... I just need an account. If wasn't my professor pushing this site, I would've moved on by now. Sign up experience (or MULTIPLE ways to sign up for all of these different things!) is very frustrating.
