Hello, Webpager
If you are able to enter on the site (that's it, the username and password are accepted and you are able to see the messages) then, after the login, click on the "Forum main page" link on the top of the screen. The go to the API section.
Now: if you receive "username not found" message, anywhere, and you use Netscape, switch to Internet Explorer. It will work. It seems that the site has a problem with Netscape (I am constantly unable to login using Netscape).
Hope this helps.
PS. If you are unable to gain access there, I can mail to you all the pages "Win32API" from UT. The zip file have 4,5 MB in .mht format. Just drop a note on my e-mail address: gdolghin@yahoo.com
