[horde] Alternative to agora for message board application

[Mike Dorman]

Hello,

Has anyone integrated any 3rd party message board applications into  
Horde?  I would like to use agora, but the HEAD version of it is too  
unstable and bleeding edge for me to use in production.

I need some sort of threaded message board application within  
Horde... and I would prefer to not roll my own.  Anyone have any  
recommendations?

Thanks,
Mike
