@john.knox, it’s me again, whirlwind of a day yesterday, so sorry for the later-than-expected response.
@BryWisteria will be back in the forum on Monday, however every 10th week we have a “catch-up” challenge, where you can go into the challenge & then post your entry either on the thread for the Catch-Up or in its own thread linked back to the Catch-Up Challenge.
During the week of the catch-up challenge, you are allowed to do up to 2 challenge entries at a time, unless otherwise noted within the challenge. This week’s challenge will end on Tuesday morning at 7 AM & then challenge will close. Then later that morning you will see the Props & Presents post. There you will be tagged for participating (should you so choose) & receive a new badge that you can change on your profile. On Wednesday, a new challenge will open again until Tuesday AM at 7.
@Mistress_Of_Herbs & I have a similar background before we came back to the craft, she is really good with what she does 
Here are a few links that may have some helpful information for you:
Experiences with the Norse Deities
Weekly Witchy CHALLENGE - The Hundredth Challenge - this challenge is closed but it will show you the basic setup for a catch-up challenge. It also lists every challenge except for the last (3? or 4?). So you can see which challenges have already been done. Bry does like to keep ideas for challenges for the following weeks - so absolutely you can request a challenge subject. Many of our challenges were from the ideas of members of the forum.
If there is a specific aspect that you would like to incorporate as a current challenge, you could also do that too. This week is 
Weekly Witchy CHALLENGE - Casual Casting & it can be casting or doing workings using informal magic which can also include chaos magic… so the challenges are open to interpretation by the practitioner.
