Freenode provides free IRC services for various well known open source projects.
Taverna developers might be present on this channel, but note that we are not available all the time. Feel free to ask any questions, even if only remotely relevant to Taverna or web services, we have still not decided on what line we're going for on the channel, so it might for instance seem quite technical.
You will need to install an IRC client to connect, there are loads available, but here is a quick list of recommended open-source clients:
- ChatZilla, a Firefox plugin (for several operating systems)
- Colloquy for Mac OS X
- xChat for Windows and Linux
Note that public messages in the channel is logged by the Apache asfbot
