RMFRP or the Rolemaster Rolemaster Fantasy Roleplaying is a version of Rolemaster RPG by Iron Crown Enterprises. This tag includes the systems published after RMSS aka the Rolemaster Standard System, but not including the reissue of RMSS under the name Rolemaster Classic.
Wikipedia has a good summary of how all the different versions are interwoven. It can get a little complicated, especially after Iron Crown Enterprises went into Bankruptcy and bits of the Rolemaster IP got sold off and repurchased.
The RMFRP tag can be used for the final system in use since 1999, but not including the reissue known as Rolemaster Classic.
