Some of the fields in this form are mandatory. Take time to be precise and to guide us through the steps that will make it possible to reproduce the issue.

               This is a simple one, but there's no guarantee that your request will be addressed.  Most of the time the responses are automatic but it's better than nothing. If in return you get an ID and/or a URI, put it in the issue comments.

               When you can't find the information about a developer, you might want to try to search something such as $COMPANY_NAME site:slideshare.net or any appropriate keywords that will make you closer to a contact. Some companies have their developers speaking at conferences about issues with performances, etc. Be careful of talks related to sales or marketing. In the slides, there is often the contact information of the developer.

               Sometimes when you can't reach a web developer, you may try to reach web designers who have also their own type of social networks such as <a title="dribbble.com" href="https://dribbble.com/" target="_blank">dribbble.com</a>. Usually they have contacts with web developers and may be able to give an introduction. In some web agencies, the web designer will be a good initial contact. Again, be tactful and don't make the life of the web designer harder in his/her own company.
