The syntax examples here follow the conventions for TOKEN and also NS in cases of server-only messages.
Syntax (nick change): :oldnick & newnick :timestamp
This format of the NICK message indicates an existing user is changing his or her nickname. If a collision occurs, see the section on Nick Collisions below. The timestamp is the new nickname's timestamp.
-Syntax (normal): & nick hopcount timestamp username hostname server servicestamp :realname
-Syntax (NICKv2): & nick hopcount timestamp username hostname server servicestamp +usermodes virtualhost :realname
-Syntax (NICKv2+CLK): & nick hopcount timestamp username hostname server servicestamp +usermodes virtualhost cloakhost :realname -
Syntax (NICKv2+NICKIP): & nick hopcount timestamp username hostname server servicestamp +usermodes virtualhost nickipaddr :realname
-Syntax (NICKv2+NICKIP+CLK): & nick hopcount timestamp username hostname server servicestamp +usermodes virtualhost cloakhost nickipaddr :realname +
Syntax (normal): & nick hopcount timestamp username hostname server service-identifier-token :realname
+Syntax (NICKv2): & nick hopcount timestamp username hostname server service-identifier-token +usermodes virtualhost :realname
+Syntax (NICKv2+CLK): & nick hopcount timestamp username hostname server service-identifier-token +usermodes virtualhost cloakhost :realname +
Syntax (NICKv2+NICKIP): & nick hopcount timestamp username hostname server service-identifier-token +usermodes virtualhost nickipaddr :realname
+Syntax (NICKv2+NICKIP+CLK): & nick hopcount timestamp username hostname server service-identifier-token +usermodes virtualhost cloakhost nickipaddr :realname
Note: Because each server normally does its own cloak generation, Unreal does not expect to receive NICK messages with the CLK info, so do not send it. It will send this info to a server it has received a PROTOCTL CLK from however.
This format of the NICK message introduces a new user to the network. If PROTOCTL VHP is enabled, the user's cloaked host is put in the virtualhost field, otherwise it'll be * unless the user is +t. With the addition of CLK, VHP is no longer necessary for determining the cloak host.
Syntax (SVSMODE): :source n target +usermodes
Syntax (SVS2MODE): :source v target +usermodes
Judging by these commands alone, you'd think they are identical. Both commands force a usermode change to occur. This is typically used by services to set +r on a user who has successfully identified. They differ in that SVS2MODE also sends the mode change to the user, while SVSMODE does not (hidden mode change).
-SVSMODE and SVS2MODE also give special treatment to usermode +d. Rather than setting the deaf mode like you might expect, SVS(2)MODE +d allows services to change a user's services stamp (which is given in the NICK message). This could allow services to set the service stamp to an easily identifiable value that could then be used to say "hey, this person identified already". The syntax of this is: +d newservicestamp and can be combined with setting other usermodes as well. The deaf mode can be set by using +d without the service stamp parameter; however, in this case you cannot set the service stamp in the same SVS(2)MODE message.

Note: Do NOT use SVSMODE to remove IRCop status from a user. Use the SVSO command for that instead.
Alternatively, target can name a channel. In this case, the mode change parameter can consist of a - character, followed by any or all of: b, e, I, q, a, o, h, or v. These characters cause the corresponding lists to be cleared of all entries. For example: SVSMODE #channel -b removes ALL bans from #channel, and SVSMODE #channel -qaohv turns ALL users on #channel into normal users (removes all owner, admin, op, halfop, and voice status). In this case, the uplink will acknowledge with a MODE listing the bans, etc that were removed.
To completely clear a channel of all modes: MODE #channel -cfijklmnprstzACGMKLNOQRSTVu (plus any added by third-party module) followed by SVSMODE #channel -beIqaohv.
