Most connections to Mibbit are provided with a random nickname on connect, usually beginning “mib_…”. On the Main Client setting up an account and registered nick resolves this for you, but on the Widget connections are left as ‘mib_’ unless changed.
This however is very easy to change so your Widget provides all new chatters with nicknames more relevant to your chat. It’s simple, just use the &nick= parameter.
For example adding &nick=Guest?? to your URI / <iframe> code turns a random nick into something easier on the eye:
Best practice is to escape the ‘?’ question mark by using %3F instead, so it becomes &nick=Guest%3F%3F
