welcome 
we run open sessions mostly on Fridays - sometimes also on Saturdays
look for any thread named V.A.L.U.E. (that is our version of Adventure’s League; although we do play various other systems than D&D 5.5 as well)
… those threads typically pop-up around Sunday/Monday
(e.g. the ones from yesterday, you could have fond here and here)
should you be interested in those 
just post in the relevant thread, that you gonna show up (and optional: which adventure pitch might interest you)
additionally there is a crowd who plays B/X D&D (~ old school D&D as seen in “Stranger Things”) if you wanna join those - look for the “Open D&D Table” threads (the one from last week, you could have found here) and shoot them a PM
