Hi,

Thanks for the great plugin you wrote! Any suggestions how I can send messages with your plugin?

see http://developer.linkedin.com/docs/DOC-1044

Any help would be appreciated!

Thanks mate..

Would you be interested in forking/expanding the functionality of the
plugin? Normally this feature I would have thought to be automatically
supported by simply setting the request path and populating $data, but as
you point out, I need to pass either xml or json.

I started to code up how I might go about doing this, I'm just busy this
week and would feel bad if you have to turn to another solution.

This may merit creating a 'LinkedinMessage' model in the plugin which
handles properly organizing the request into the correct format. I've been
talking to another dev using the plugin about fleshing out it's features to
include models anyways.

Have you worked with POSTing xml and/or json before?

I added a commit and a theoretical implementation that may enable you to do this. I would recommend playing around with it and seeing what you can figure out.

I'm sort of busy atm to do any testing and confirm, so if this is urgent for you perhaps you can help me out. I'll be happy to lend whatever support I can.
