Which one to install? and what does it do?

[allyr]

Hello! 

Ok I have started reading this site - but have ended up a little overwhelmed and out of my depth!

I currently run a forum using SMF and was told it would be a good idea to have a portal.   The version I am using is Forum version: SMF 1.1.4.  The link to my site is: www.singleparentaustralia.org.au/forum

Can someone please assist me with exactly what this does to my forum when added and which would be the right one to add? 

Thanks very much!
Ally
