What's an Issue Connector?
An Issue Connector is a simple way to connect your repository to your issue tracking system. After setting up an Issue Connector and connecting it to a Repository you've set up, every check in made to that repository will have its commit message parsed by the Issue Connector. The Issue Connector will take the commit message and apply a regex to parse the information the issue connector needs to generate a link . After the information is extracted, the issue connector generates links to your issue tracking system and displays the links tracker. The links generated are displayed in the build those change sets were applicable for.

Verifying the Regex also protects you from the Server URL wanting more group values than the Regex is told to match and return. For example, the following image shows what happens when the Regex is told to match only one group but the Server URL requires two. Notice how the Regex field does not contain a <project> group.
Finally, Verifying is most handy for checking your Regex validity. In this example, I've set my Regex to match any amount of numbers preceded by a # character. The dummy commit message I've supplied however does not have that pattern any where in it so I get no matches.
