I've tried using the demo on http://www.igniterealtime.org/sparkweb/ and there are many bugs.
- There is an option to create account but the button 'create' doesn't work.
- Adding chat server and friends sometimes just hang without a response.
- I used two browsers and tested it for a couple of minutes and sometime messages are not arriving.
- The GUI is not clear and the responses when performing an action are slow and confusing.
In the past you advertised BOSH support as stable although it was terrible.
I've wasted months trying to use it while you knew it is completely broken.
I know it is an open source project...
Does anyone really use this client on a big scale with success?
