Main details about your organization can be edited any time by going to your Organization Management page and from the "Admin" drop-down menu, click "Edit".
Add to or change any of the fields to edit the information displayed for you organization. Be sure to save your changes before navigating away from the page.
Note: If you get an error page when you save something, it was likely the fault of a "time-out error" caused by being on the same page for a long time. Not to worry, even if you see an error, the information was likely saved. If you experience this, be sure to check if your content saved before attempting to do it again.
