[HacktionLab] Forum software recommendations

[Marcus Valentine]

I'm looking for recommendations for forum software. This will be used by
a community orchestra. It will be private, so won't need a public facing
sign up facility.

I guess the features I am interested include:

* A straightforward and logical admin interface;
* Not too heavy weight, as the volume of messages and number of users
will be in the 10s rather than hundreds.

I used phpBB years ago.

Thanks

Marcus
