Is there a plug in or easy way to cross-post entries to two or more blogs?

You can try http://multipleblogs.itpatil.com. I personally use this software to post entry to multiple blogs.

Um, no.
I've never heard of this tool, and I watch a lot of feeds related to MT. That's not necessarily meaningful in and of itself, but strangely and coincidentally enough, this is also the first post from you, ever, in this forum. Sorry to be paranoid, but do you have any connection to this? Who are these people and why should they be trusted?

To point out the obvious, this thing is requesting your login credentials. Providing your password(s) to a third-party service is generally considered an extremely undesirably practice unless you know exactly who you are dealing with.

Yes. Good point. I work as a developer and developed http://multipleblogs.itpatil.com in my free time.

You are correct about 3rd party and security issues. But then again, I don't know of any other way to do multiple blog posts to different types of blogging platform (i.e. wordpress, MT, blogger etc) without using the XML-RPC protocol (which requires API / login credentials) ;)

In any case, the whole point of the exercise is that I use the software and if it's helpful to anybody else, then great.

Anyways, thanks for your reply.

This plugin may be what you need http://plugins.movabletype.org/crossposter/

Thanks for the info - i never even realised that posting to multiple blogs was even possible!
