Forum Introduction Body on each of my forums.

For some reason what I put in the box and submit is not showing on the Forums (indeed when I submit, the confirmation page doesn't look normal - there is no message). The text that was there previously remains.

I need to change the text that is there on our forums, so while I would like to be able to fix this normally in the short term I would like to alter that text quickly as it is out of date. Is there a way to do that?

(And why might this be happening?)

Thanks
