I have used OCS since 2003 for a couple of different conferences. Here are the URLs that I tend to use.
For the organization's main website: http://www.imrf.info/
And then, for each year, we use: http://www.imrf.info/2006/ http://www.imrf.info/2007/
Of course, for this year's conference, I would like to use: http://www.imrf.info/2008/
and then continue on with /2009, /2010, ...
When I installed the beta version of OCS 2, I was a bit confused about what directory I should install the application into. That is, in order for my conference URLs to continue to work in the same fashion.
I am now ready to install the real version of OCS 2 (in fact, my client, the conference organizer is MORE than ready for me to install it!) and I would appreciate any advice you can give me.
