Is there a way to remove this limitation for app related tags? I want to ask a question to the developper of an app, but as it is brand new, the app- tag doesn't exist... (specifically, it's about app-puppet-simony)
Basically it's to protect against spam and ensure the community can control content. You probably need to have accumulated 15 reputation points (by posting and being voted up) to create new tags. And the assumption is that a title less than 15 characters is most likely not descriptive or informative, hard to search for. People should not have to have to click through to a post to find out what it's about.
