ok, I get the idea I think. that example you posted is no good because you have to be logged in to see it.
however, this is not something you can do by simply editing the html. it would have to be a MOD created for phpbb 3.0
the problem is that phpbb 3.0 is reaching its end of life status and no more MODs are being accepted for it.
the first thing I would do if you do not want to upgrade to 3.1 would be to choose a different style. that one is very poorly written, it has mistakes all over the place in the code and it is hard coded with a lot of images and language other than english etc.
but, like I said, you can't get what you are wanting unless you find someone to write up the MOD that creates it. you can't do in normal phpbb at all. even if you upgrade to 3.1 you would still have to request someone to create a extension for you that would add that type of function to phpbb.
I'm baaaaaccckkkk. still doing work on donation basis. PM your needs.
