# Changing the link num

The `SB_SETUP_SETLINK` command allows you to change how **AdminBot** sends events to your script.

By default, AdminBot sends events to `LINK_SET`:

```csharp
llMessageLinked(LINK_SET, SB_CHAT_MESSAGE, slname + ": " + message, slkey);
```

If your object contains **many prims**, this may cause performance issues.

To change the default behavior, use the `SB_SETUP_SETLINK` command like this:

```csharp
llMessageLinked(LINK_SET, SB_SETUP_SETLINK, (string)LINK_THIS, slkey);
```

The new `linknum` will remain active **until reset**.
