100th Request Milestone!
Congratulations to Kevin for completing their 100th request!Winter C3 and Other 2023 Event Updates
I know everyone doesn't like it when we make big sweeping changes to the events calendar, so good news: we won't be doing any of that in 2023! Instead, we'll be getting it out of our system early before the new year rolls in!!Due to a combination of staff availability, convenience, and Eastern European Religious Events, we will be moving Winter C3 to February 10th-14th. And while Summer C3 will remain in July this year, starting in 2024, all future C3 events will be hosted in February/August. We feel that moving both events forward a month will make it more convenient for us to prepare for these events, and offer better timing for everyone to participate!
So what does that mean for other events? Well, you now get a contest early! QLDC 2023 now starts next week Friday, January 6th! We will also be moving CLDC 2023 forward to March 20th to make room for...something else.
And one last note: you can now check the front page of the site's calendar for all of the listed events! Make sure to check regularly for new events (and possibly other things?) we decide to add to the calendar. Thanks for kindly accepting all of these new changes to the calendar, and have a Happy Two Days Before New Years!
