- 2. If channels are not local then /join silc@silcnet.org, will create
- connection to default if it is specified in the silcd.conf and if it
- isn't or join fails it creates connection to silcnet.org and sends

- 5. If we create connection to a remote that already has a channel that
- we also have as a local channel, should we merge those channels?
- Should I announce my local channels when I connect to router? Should
- I keep local channels local, unless I say /join localch@silcnet.org

- 6. After we have connection established to router, depending on the
