>>>>>>>>>>>>> opened up this doodle poll
>>>>>>>>>>>>> <https://doodle.com/poll/xm8aerdgbtt5qsgd> to set up a time
>>>>>>>>>>>>> that's best suited for those interested to participate.
>>>>>>>>>>>>> I've set a placeholder recurring meeting to monthly for which
>>>>>>>>>>>>> I'll adjust the day/time based on the doodle poll results, and we can
>>>>>>>>>>>>> adjust frequency based on how useful folks find it. The meeting information
>>>>>>>>>>>>> can be found in the above google doc.

>>>>>>>>>>>>> Please let me know if you have additional feedback or
