How do I add an idea?
Select the 'New Idea' button and choose the category that your idea belongs to, then add the idea title and the details related to the idea.* Ideas added without any details may be rejected.
Hootsuite use the exact same image editor as you but offer more features including the ability to add a soft focus layer to the image, extra resize templates including Twitter and finally being able to adjust image brightness, colour, saturation, exposure etc.
Here's the link to Hootsuite's video on using the same image editor. You'll see the extra features along the left edge of the screen.
Many thanks, kind regards, Peter
