[RTTY] ARRL RTTY Round-up warm-up?

[Bob Burns W9BU]

It's only the first day of the new year and I have already lost my mind.

Seems like I saw a message somewhere on-line that talked about a couple 
of warm-up sessions on Friday evening and Saturday morning for the RTTY 
Round-up.

Does anyone have the times or can anyone point me towards the message my 
now dead brain cells thought I saw?

Thank you.

Bob...
