@pietercolpaert I do not think there is a specific section about tooling but …
- For the forum (and over time mailing lists) we are moving to this discourse powered form http://discuss.okfn.org/
- For community directory we are using profiles and badges here
- For chat (esp for labs but generally) we have a thread here (current favourite is slack): Text Chat Space for Labs - IRC or Slack or XXX
- For call hosting there is this thread: Web conferencing for community calls - BigBlueButton server hosting
- For a wiki i increasingly think moving to github pages powered sites is a good idea but that is to tbd - we have done this for e.g. OpenSpending http://community.openspending.org/
