If you’ve found a bug, or have a feature request my WordPress plugin Job Manager, please submit a new issue on the development site. Due to the volume of email I receive, things can get lost, so it’s a better place to track issues.
For anything else, feel free to contact me using one of the methods below. Please note that, while I’m frequently online, I may not always respond to IMs immediately. Email is the best method to make sure I a) get your message; and b) can give it the appropriate attention.
