Which extra for forum/community under MODX?


I want to make a small forum/community under MODX but Discuss doesn’t want to run under MODX 3.0 version.
It is also an old add but I didn’t found something else.

Do you know one add on for doing this ?

I don’t know if there’s an extra for it or not, but I’ve heard that vanilla forums is easy to integrate with MODX.
