sure i got you there mate, but its not as easy as it shows.
I can create an id before the class to remove it but the only location i can find is the page_container but it still removes the titles from my threads, just want the home page.
i have located the <div class="titleBar"> > PAGE_CONTAINER then i search for the class and i add the id="remove_hometitle" add to extra.css yes it removes from homepage but it also removes from all threads
You can surround the h1 with:
... h1 stuff...
For the above, if it is not the index page, no h1 title, otherwise display the h1 title. However, that will work on forum home, I never used a portal so can't say it will work for you.
