The plugins site is currently in development.
We've been looking to provide a higher-quality, spam-free experience at the plugins site for some time, and a major error on our part forced us to shut down the current site before we could put the new one in place. We are developing a new site, and you can follow along with its development on GitHub. For more information about this transition, including steps you can take as a plugin author to prepare, please read our post about what's going on.
No Spam 1.3
The release of Version 1.3 focuses entirely on allowing multiple dots (.) in e-mail addresses. Please note that at (@) signs are now replaced with two forward slashes (//), so current implementations will need to be updated before you can upgrade to version 1.3. I have also updated the PHP function to reflect this. See the demonstration page for more details.
