What LMS / VLE do you use?

I am interested to find out what LMS / VLE do other Xerte users use?

What pros / cons have you noticed, compared with other LMSs / VLEs that you have used? especially in relation to hosting Xerte (SCORM) content.

My institution use Blackboard and I am currently experimenting with SCORM settings etc with the hope of delivering accurate results.

Thanks
Lewis
