[PL-sem-jr] [Reminder] PL Jr today at 2

[Hyeyoung Shin]

WVH 366 is not available for Wednesday 1pm - 2pm. Ashley will look for one
outside WVH and get back to me.

I will close the poll today. If you haven't indicated your availability but
intend to come to the meetings, please do so by 5 pm.

Thank you!

Hyeyoung
