Rants can be made by clicking the + New button button at the top of the webpage.
In the Post creator you can create your rant, and upload photos and videos. You can add trip members in the Tag section of the sidebar.

All posts are accessible to the public by default. This can be changed in the post editor by:

Opening up the sidebar by the button by the top right.

Then scrolling down to the 'Groups' tab and entering either
 Registered - Visible to website members
 Current member - Visible to the website's list of current ULSA members

into the 'Read' box. This does not guarentee posts will be kept private, if the website malfunctions. Keeping this text box blank will make the post public.

Please get in contact if you have any queries or issues.
