text-transform capitalise

[iA1]

If you want the whole title to be in uppercase, use:

text-transform: uppercase;

Edit: I think I have misunderstood. You already have the title in uppercase and you want to capitalize only the first letter. Then use the function given in your link as javascript.

That function will apply to all p elements on the page. You might have to add specific id or class to forum title first and then use this function.
