Question about ERC nick completion

[Francis Moreau]

Hello,

I have a question for ERC users:

On a channel, some nicks are prefixed with ".@" chars. I don't know
what it means (since I can't find any mention of it in the ERC info
pages) but the nick completion doesn't work for them. Some other nicks
are just prefixed with "@", and in that case the completion works.

Could anybody tell me what's wrong ?

Thanks
