I already posted before but unfortunately on the wrong topic about 3 columns.
I refer to TREAC also a difficult layout.
Check it all out on http://www.indocommunity.net
It is in Indonesian language but please surf around a little bit if you like the layout.
Indeed as mentioned before the CSS is still not stable yet and still a lot of work has to be done the CSS file is still full with rough code.
Because I think a lot of members will like the theme I will make it available in a later stadium when it is more stable and reliable.
If there are any suggestions please let me know.
One more remark WordPress can give strange results when new messages are send within this theme.
The solution seems to be to start new sentences on a new line after an Enter.
The HTML does not seem to be the problem.
