Robust and modern FOSS forum engine.
Great core team and friendly community.
Powerful full-text search, good plugins and easy to customize.
- assign moderators and staff per-category;
- let login with phone # (i.e. without email) out of the box.
Happy using it for my projects:
Eve.QA - easy and expressive Q&As for events.
Oprium.com - a place to share and discover exciting opportunities.
Apteka.TJ - forum on health, beauty and family well-being.
