I'm figuring out how to test this in ICQ

[mk6i]

If you can provide some steps to test w/ other clients that would be helpful

[siohaza]

I did tests with QIP 2005, Jimm, and Kopete from TDE all are playing nicely and all 3 have Xtraz support. Right click and set some status with the text, then write to the contact and you should have his status and the text in the response back

[mk6i]

I'm having so much trouble getting kopete/QIP to be stable in ICQ mode that I can't really test this yet. I will start doing some ICQ work for the next release so that I can get it stable enough to test.
