BOINC Challenges are on hold for the moment, so it's a good time to plan for PRPNet Challenges.

GCW will move to BOINC soon. C109 is the current range being tested in PRPNet. C109 has just been sieved to 66T in BOINC, however it was previously only manually sieved (500K <= n < 1M) to 30T. So GCW is not a good choice for a PRPNet Challenge.

WFS and WSS don't have working checksum support. Any work we do on these may have to be redone (my opinion only). I am waiting for Mark to have a look at this and post a new version on his web page:
http://www.mersenneforum.org/rogue/rogue.html

So that leaves us with 121, 27, FPS and PRS.
I suggest the following initial plan:

beware of the Ides of March!
I suggest we start on 16th and made this my birthday run ;-)

middle of April will be an offline-race because of my planned holiday

I think stats will be available ...

Suggested themes for March 121 Challenge

http://www.wincalendar.com/Holiday-Calendar/March-2017
St Patrick's Day, 17th March

https://en.wikipedia.org/wiki/International_Day_of_Happiness
The International Day of Happiness (known as Happiness Day) is celebrated throughout the world on the 20th of March.

March 20 - March Equinox. The March equinox occurs at 10:29 UTC. The Sun will shine directly on the equator and there will be nearly equal amounts of day and night throughout the world. This is also the first day of spring (vernal equinox) in the Northern Hemisphere and the first day of fall (autumnal equinox) in the Southern Hemisphere.

Maybe the Happy St Patrick's Equinox Challenge!
A 5 day Challenge on the 121 Project starting on the 16th March.

Next challenge is:
16-21 March - 121 "Happy St Patrick's Equinox Challenge"
I suggest we start at 12:00 UTC and end at 12:00 UTC.

Thanks for the suggestions. If someone seconded might have gone with one of those.

stats are ready at the well known URL http://u-g-f.de/PRPNet/challenge_stats.php
do we make challenge threads this year or do we post the few races in this one?

I created a March challenge thread:
http://www.primegrid.com/forum_thread.php?id=7343
We can do more challenges than the initial list, if it makes sense to do so.

I've confirmed that the new LLR version 3.8.20 works with PRPNet version 5.4.0.
Can't see any way to pass command line arguments to LLR though.
Mark thinks PRPNet could be modified to allow multithreading.

Let me know your own ideas or opinions.

I say Star Wars day as the start of the challenge. The 15 day PSP challenge is plenty enough for this month, so May would be a good place to start.

It's time for one of my favorite sub-projects, a Factorial challenge.
We're coming up to a big n=250k Milestone.
Ideas for challenge themes:
• September 22 - September Equinox. The September equinox occurs at 20:02 UTC. The Sun will shine directly on the equator and there will be nearly equal amounts of day and night throughout the world. This is also the first day of fall (autumnal equinox) in the Northern Hemisphere and the first day of spring (vernal equinox) in the Southern Hemisphere.
• Number Theory Methods in Cryptology - September 11-13, 2017 http://duch.mimuw.edu.pl/~nutmic/
• Fun Factorials Challenge

Let me know what you think.
Any ideas you have are most welcome.

personally I prefer the later september, Equinox sounds fine
