Today I noticed a pattern on the homepage (https://ribblr.com/pattern/cozy-rib-cowl-crochet ) with an icon showing that it will have a CAL in three days time.
I happened to notice it by luck of the front page lottery. If I had hit on a different array of patterns, it wouldn’t have shown up.
Would there be any way to have an upcoming event tab to showcase these in the future?
Hi Stephanie and thanks for the feedback!
Yes, it is going to be implemented in an upcoming update. 
Excellent! Thank you.
Hi! Do you know when the next CAL is going to happen? I would like to join one, but I just haven’t seen any yet!
There was a CAL hosted recently by @stitchingwithsab ! And we’ll have more exciting CALs and other live events this year, stay tuned 
Thank you!
