[wp-hackers] Update profile page from external page

[Kim Parsell]

I've got a tutorial on my site about allowing/limiting user access in 
WordPress. I had a comment left regarding the tutorial, and in the 
comment, they asked about posting an update to a user's profile without 
going to the actual WordPress profile.php page. Link to comment is below:

I'd like to pose this question to the experts on this list, to see if it 
is possible to do what the commenter is asking. Please feel free to 
chime in either here or in the comments section on my blog as to what 
is/isn't possible.

Thanks in advance!

Kim
