Guess I'm just too stupid to figure it out.
Here's how I did it, Earl :
1.) Click the "Login" link at the top right corner at forums.smithmicro :
2.) Now click on "Get a Smith Micro Account."
3.) If you have a Renderosity or Content Paradise account, you can sign up to the forums by using those accounts. If you don't have a Rendo or CP account, then just fill in the text fields and create a new account.
4.) If using your Rendo or CP account to join the SM forums, put in the login information you would use on those sites, on the next page :
5.) The next page will ask you to authorize access. You need to click "Accept" in order to allow the connection (and allow yourself to login to the SM forums using one of these accounts :
6.) Once that's all done, you'll be looking at a page that's rather... devoid of any useful information. There's NO confirmation message on the screen. But at the top of this screen will be a text link that says "Forum." Click that, and you'll be taken back to the SM forums.
7.) Now, you have to actually log in to the SM forums. So look back up to the upper right corner of the screen, and click the "Login" text link again. Again, this is a bit convoluted... but this will take you back to the login page. This time, you want to enter the login information that you signed up with. (So if you linked your Rendo account, then enter your Rendo username and your Rendo password.)
8.) The system will give you an error about an invalid password (if you signed up using a Rendo or CP account). That's fine. There will also be a message that "You may have signed up with a partner account. Click here to change your password." From as near as I can tell, this is not going to change the password on your Rendo or CP account; it's just going to give you a way to set a password for the SM forums. Choose a new password, and click the blue "Save Password" button.
9.) Once again, it's going to get redundant. You're going to be looking at another page asking you about changing your password and saving a new password. Ignore that, and go back up to the top of the window and click on "Forum" again. Now, once AGAIN, click on "Login."
10.) Now, enter the username that you previously set up (if you linked your CP or Rendo accounts, enter that username) and enter the NEW password you just saved.
11.) At this point, you SHOULD see something like this. Click the blue "allow" button.
Once you've done ALL of that (I agree that it's really unnecessarily clunky and convoluted) - but once you've done all of that, you'll be taken back to the forum's main page with all the messages and categories and such. You'll notice that the alerts are all there; there will be an alert showing unread messages, a system generated notice welcoming you to the forums, and... you'll see your reply buttons when you click on a thread.
I think the sign up process could use a little cleaning up - and a couple of the pages could definitely use some clarification. But it does work. Thankfully, you only have to do this process once. After that, you can just go to the forums and login normally...
Hope this helps.
