More likely project development section is meant for the development of the project. You can use announcement section if you are trying to convert this thread into your ANN thread. This section is more likely for the developments rather then any membership updates, etc.

ANN thread and Development thread and entirely different. Development thread is meant for finding new devs, repairing the site, etc and announcement thread is meant for Announcing the features and skills of the project. Announcement thread should be something attractive as it playes a major role after the website. Peoples like going to the ANN thread before they go through your Web.
