When the main feed is busy, posts may fall from the homepage. However, some of our members click directly to the category they're interested in via the homepage - as shown below:
Make sure that you put your discussion in the correct category, you never know who might miss it. It will also give your post a little extra visibility to members scrolling through the categories.
The category selection will appear underneath the text box when writing your discussion post, simply scroll down and choose the correct one!
