Yes!! Got them to work! Brain is just a bit slow is all!
For anyone that needs to make links work with a Mac (like me) and can't use the link button (as shown for PC users at start of thread) this is what works for me. Be warned I don't know the technical terms for these things!!
Go to the WIP you wish to use in the wip thread and click once on the first 6 digit number at the top of your post in the Yellow bar,( should look something like 113243 in reply to 113227). This changes what is written in the bar at the top of the screen. Go to this bar and highlight it, (turns Blue) then go to file and copy it. Next, go to the Finals thread, click in your post where the link is going and select Paste from the file option. You should now see some text starting with "http:// blah,blah" there. Go to the beginning of this text and write URL (in capitol letters) in these brackets [ ]. Then go to the end of the text and put /URL in the same type of brackets [ ].
Go to "post" at the bottom of your screen, click, and voila, you should have a working link when the page reloads. Repeat for all the WIPs you require.
Hope my long winded explanation helps someone!
