I am by far not a large stakeholder so that I may not be the one who could really help you on all front.
I would however be very happy to support the STEM part of your review (note that we have our own at STEMsocial, released as a STEMmsocial distilled every Monday/Tuesday). As long as you promote posts that are in line with our guidelines, you can count on my support for the Tuesday post.
Thanks a lot!
