If you would like to get in contact with the developers of WordPress, you have a number of options.
We can’t do email support, because it’s not a good way to help out a lot of people. If you are having any trouble with WordPress, the best place to go is the support forums, where a number of people might be able to help you with your problem and others can learn from your troubles, or the Documentation Codex.
There are numerous ways you can help out the project, which we’ve tried our best to outline on the Codex in Contributing to WordPress.
If you think you’ve found a security problem in WordPress, please see the Security FAQ for information on reporting the problem. (Note: Any non-security messages are ignored and deleted. This includes requests to take down sites or delete posts for legal reasons. WordPress does not have the power to take down or in anyway alter the sites that choose to use it. Please contact the site’s hosting provider.)
