Should you be interested in learning more about Juniper devices, this free training is a good place to start. There's free training for all levels (yes, including the expert level).
For the Cisco engineers that are curious, there's an accelerated course specifically for CCNA -> JNCIA.
There's also discounted vouchers available for each course completed.
Please make mod tools a top priority. It's absolutely asinine that I need to have someone comment in a community to add them as a mod.
