This is an attempt. Remove thr block environment if you don't want it. Note the skills mentioned in the comment provided by @cfr are the commomly seen skills since a poster is usually over sized and those approaches will be easy to design the layout and debugging.
Update: This update includes the columns and column environments. A total of 3 columns was demonstrated here. Left column and R column (which has R1 and R2 columns) and thus 0.28\paperwidth, which is adjustable, is used. Often time, the begin and end column(s) are the main sources of errors when working on beamerposter IMHO.

beamerposterpackage was recommended here and I am trying to learn how to use it. – merlin2011 Jun 05 '14 at 00:31beamerposterfor a few posters so far; it seems to work well for the task. When you think about it, it's the same idea most Office users go for—a Powerpoint with only one gigantic slide. – Sean Allred Jun 05 '14 at 01:06example.texit uses severalblockenvironments in a singleframewithcolumns. It specifies\titlebut does not use\maketitle. I would try basing your own poster on the sample poster and see if that works better since the example basically seems to be the documentation. – cfr Jun 05 '14 at 01:24maketitle.
