Forums Scripts & Popups jabber and mirc

I would like to know if there is a plugin to connect to jabber chatrooms from mirc.

In order to answer your question, that would require us to understand your question.

Jabber chatrooms are..?

Sigh.

Try google? sigh.

The first match on http://www.google.com/search?q=jabber clearly explains what Jabber is-- in fact, the very next match is conveniently titled "What Is Jabber?"

Anyway, to the OP:

Google would probably help you as well, more than we can anyway:

http://www.google.com/search?q=jabber+mirc

Otherwise try www.mirc.net or www.mircscripts.org, but I don't think I've ever seen one personally.

Just to add onto this, IRCap contains a jabber script. I'm not sure if the author allows it to be used outside of IRCap but it could still be handy to learn from.
