Well, this is just as good of a place to post this as any:
I managed to get my beta sign-up to go through after having significant difficulty with the process yesterday. It worked fine today though, so here I will highlight what my problem was, what browser I was using, and how I fixed it.
Browser: Firefox 3.0 with various plug ins (IE tab, ActiveX just to name a few)
The Problem: I was having trouble getting to my account to alter the "Interest in Beta" option. Whenever I entered my info to get to my account info, I would get kicked to the forum account sign-up page. I would enter my old info to try to log into my account, only to be kicked back to the same page.
The Solution: Using firefox, I went to tools -----> clear recent history ---> everything.
I then clicked "forgot password" and typed in the email address I have registered with this site.
Logged into my email account and clicked the link in the email this site sent me to reset my password. I kept the same password info as I had before, but you guys can change it if you want.
Go to "My Account" again and login using your email and password (the new one if you changed passwords).
From here you should be able to access your basic account info now. Click the "yes, I'm interested in beta" option and click "Update."
Now, this is kinda an important bit, you get sent to the beta test user agreement screen. Above the user agreement, there should be a small black text box with white lettering saying "Your account has been updated successfully".
Cool beans right? now agree to the user agreement, and enter your extra info for the beta signup screen, fill out every text box (including the second address line and second phone number, also with the phone number, don't include any dashes or anything like that.) Click "update" or whatever you need to click and it should send you to the scan page.
Make sure you have ActiveX installed. (If you don't the blue holobar the droid is projecting should turn yellow, and you should be prompted at the top of the page to install activeX right on the spot.) If you do, the scan should take a few seconds, not very long at all. Once that is done, it might send you back to the user agreement page, but don't worry, your info should all be saved, all you're doing at this point is confirming what you put into the info page.
Do the scan again, it should take less time than it did at first, click finish and poink! you are signed up for beta now... WOOT!!!
Hope this helps at least a few people
