has been retired.The Developer area now is DEVELOPER.OPENTEXT.COM (Requires a Self Registration based account)
Nothing much but since OT (Livelink) material is not free to come by severely restricted by licensing/protectionism et al
Communities was a livelink site OT maintained free to users who registered
Oscript Questions and many many examples
Most OT programmers who are in this business for some time have accounts to Livelink’s Knowledge base and it is fun
believe me.I just published these so that starting developers have some material if they are self taught.
