That's easy to fix!
Go to "My Home
" on the top left corner of your page. Scroll down to Settings and Options on the left side of that page. Click on "Edit Options
". Scroll to Thread Display Options
and there's a box that says Thread Display Mode
. Change the drop down box from Linear - Newest First to Linear - Oldest First.
That's what my settings are on, and I see the oldest starting posts first. Bill's post above explains the differences between the options you have, if you want to use the threaded settings. (I don't use them). That should fix it for ya!
