Help Wanted
The first place to look at when you have a problem is the KVIrc bug tracker.
If something goes wrong, or if you have a question, a suggestion, or are simply interested in KVIrc development, you can report on the KVIrc bugtrack.
The developers follow the bug tracker and will answer questions as soon as possible.
The official KVIrc support channel is located on the Libera network and the channel is obviously named #KVIrc.
