There has been need of a good place for tracking raid progression for a long time for SWTOR. While many different progression threads have popped up they only go so far and don't provide any sort of verification. Since this is a young game an API for developers to query servers and determine objective rankings has not yet been developed by Bioware.
We at Retribution have hopefully come up with a system allowing for tracking raid progress in a community moderated way that can eventually evolve in to a more objective system once an API is released.
The site is brand new as of 3/27 and is now in opened beta. We expect that there are many issues that may need fixing going forward and encourage people to use the site and give us their feedback and criticism. At the moment there are only a few of us developers working on the site, so please be patient while we work to fix bugs.
