Command: /mode nick +[a-zA-Z]

Function:
<do command>
<join #channel>
/* no one can see you until you talk or send a raw to the channel */

Something similar to +D but I want it to be an user mode, not channel mode.

Rant about it

i really don't get what you want. are you talking about a walkover mode or something ?
like +D but for yourself?.

if yes, imaging how this could be abused..

I'm afraid this feature wont happen, xplo he means a version of the channel +D mode for the user where it would apply to every channel they join, this feature wont happen because the channel ops have the right to decide if the channel can see who joins or not, not the individual users.

This idea would only serve to generate more abuse.

This is exactly what i ment, "+D for yourself"
Thx for clarification.

Users also have their right to stay secure... in some way

toolz, it doesn't make any sense. What it has to do with the security? That mode would rather mean something private, nevertheless +D as usermode wouldn't make any sense, at least in my point of view that's how i feel about it.

toolz and in this case, they would be more secure without the mode, as such a mode would also protect abusers whom would abuse the feature for the exact same reason the idea is being suggested as good for users, from a technical standpoint, the potential for abuse far, far outweighs the supposed security gains.

Best example, Spammers would love this idea.
