For a list of RP orgs (both player-based and fictional for stories purposes) and their descriptions, have a look at this page on AO Vault.
Note on org classifications: You probably have noticed letters behind the name of certain of the listed orgs. This is a project of 'classification', meant to help people in their choice of an org. All of us don't roleplay the same way, nor are looking for the same degree of RP involvement. So, hope this can help.
Org type A
An org where RP is casual but present. 'Regular' players and roleplayers are mixed. An org to join for a light experience of RP without getting too deeply involved into backgrounds and rules of conduct.
Org type B
An org where RP is common. All members are able to roleplay when they want to. A polyvalent org where all kinds of attitude can cohabit freely.
Org type C
An org where RP is required. Some stories can be prepared, members happilly join roleplayed conversations, yet are also involved in other aspects of the game.
Org type D
An org where RP is very present. All players are ready to be involved into stories and roleplay naturally. In Char talk is applied, yet some liberties are allowed.
Org type E
An org where RP is everything. All members are experienced roleplayers or learning to be. Stories and backgrounds are what leads the org, other aspects of the game are secondary. Out Of Char talk is restricted.
