/as field Age add
/as field Age set whois
/as field Age set remote
Now you want to set that information:
/set <nick> age <data>
/set John age 20
Now everyone will be able to see this when they do:
Or they can do:
/get john age
For another example take a look at how we implemented avatars at the end of this technical note.

As an example when we decided to implement avatars we used the Field system. First we created a new field called AVATAR. Then we set it so that when user joined a channel the field would send to all other clients in a channel. We set it to broadcast to all others in a channel when it was changed. With just these settings we were able to code the java client to support avatars.
Avatar Field Configuration:
field avatar add
field avatar set onjoin on
field avatar set onchange on
field avatar set remote on
The java client has several params for avatars that let admins define graphics that will be used when certain the field AVATAR is set.
<param name="avatar" value="0=avatar16/alien16.gif Alien">
The first is the param name, Then the path and file followed by the field name.
When you select an avatar the java client will set the field avatar with the field name and display the graphic that was specified in the avatar param.
