What time would get the most participation for Drupal Initiative Windsprints?

For the month of April, we hosted "office hours" for the mobile initiative on Sundays, but attendance was poor. While discussing it with JohnAlbin on IRC, I thought maybe initiatives could combine office hours and get a synergistic benefit.

Then I also had a brief chat with xjm about the nature of core contribution mentoring times and how they are not the same as what is needed for core initiatives. Core initiatives focus on new development and tasks are sometimes larger and/or not as well defined. However, the issues for core initiatives would still benefit from regularly scheduled mini-sprints.

So, I am offering to host core initiative wind-sprints once a week. If initiative leads have time and inclination, it would help to tag issues appropriate to windsprints. Otherwise there would be no requirement for them to be in attendance any more than Dries is in core office hours. Obviously we'd love to have participation tho!

Just trying to get a better idea of what time would give us the most participants here.

Thanks!

One thought, which I said in IRC but can post here too.

Rather than try and come up with a new 2-hour chunk of time for people to find space for in their calendars, another idea is to co-locate these mini-sprints with one of the Core Mentoring Hours slots.

Rationale:

• Those time slots have been shown to already work for at least some people
• people come to CMH looking for stuff to work on, mini-sprints offer stuff to work on (and important stuff at that!).
• CMH also routinely suffers from lack of expert Drupalists to be on hand to answer questions from new contributors. Mini-sprints offer Drupal experts. ;)
• It allows CMH to be attractive to non-beginners as well, and also gives a logical level of "graduation" to people who've already done their go-around with issue summaries or novice patches.
• We only need to do a big PR/Twitter/etc. push around one event, and not two.

It seems pretty win-win to me, but I'm assuming those specific time slots were chosen for a reason, so this might be a horrible idea. :) Just a thought.

It's really hard for me to commit to a 2 hour block of time during the week due to work. The odds of me being able to do so consistently for WSCCI are sadly low.

Also, I'm in Central time. That means only one of the above options happens while I'm awake. For anyone on the west coast, they'll miss every one of them.

I'm happy with anything after 9am Central on Fridays. Really options should probably be Pacific based if we're catering to the North American Continental dwellers.

How about 1 pm Eastern (5 pm UTC)? On Fridays?
