Yeah, I think that you're missing that you've gotta go OUT of a thread and up to the
Off Topic Forum board index page first - if you look up the top left NOW, (as you read this) you will see the Red '+ Reply to Thread' tab, but immediately above that is a link to 'Wrap my Spyder' (usually) & then above that is a Red line of text with a little house to it's left. This line shows you where/how deep you are into the Forum & sub-board structures, and in this case it should show
Forum, General Discussions, Off Topic Board (all in Red) then the thread title '
A Hardtop Electric Spyder?!' (in black) - can you find that? :dontknow:
Once you've got that, if you click on 'Off Topic Board' in that Red line, it'll take you directly to the board's index page, where all the various thread titles are listed in most recent activity order, with a little more info displayed as well. Buuut, once there, the Red '+ Post New Thread' tab is almost the same colour and it is in the same place the 'Reply to Thread' tab is here/now on this screen (ie, when you're looking at the content of a thread), but once you're on the Index page it is swapped for the tab for '+Post New Thread' - and clicking on
that is the tab that lets you start a new thread.

hyea:
Ps: there's another '+ Post New Thread' tab waaay down on the BOTTOM left of every Index Page too, just to make it easier to find one when you need to.
