First of all, thank you both for responding on my question. I thought doing something like this: Asking the user to allow my twitter app gain access to their account. After that, redirect the user to a page where I'll get his username using Twitter API. Then, redirect him back to my site after I've put his username in my user database.
What do you think about that? Is it possible at all? -- Twitter developer documentation and resources: http://dev.twitter.com/doc API updates via Twitter: http://twitter.com/twitterapi Issues/Enhancements Tracker: http://code.google.com/p/twitter-api/issues/list Change your membership to this group: http://groups.google.com/group/twitter-development-talk
