Advertise my website/app

This is my app website: [login to view URL] Please read and make sure you understand what the app is designed to do. You should have a good technical understanding. There are some forums where people have the problem of lost windows in OS X (e.g. Google keywords "OSX lost windows" or "macos windows off screen"), Post a reply recommending my website/app in a modest and polite way. You should have a rating on stack exchange that allows you to post answers. Any other ideas of advertising the site are welcome. But this should be limited to the budget
