How should we exploit synergies between JWST and other telescopes such as ALMA, LSST, GSMT and others?

21cm experiments. We need some form of coordination with 21cm experiments currently under development. They will be fundamental for the study of reionization.

What about GRBs? It is important to have a GRB finding mission up when JWST flies.

Early legacy call. An early legacy call for proposals well before JWST launch might enable people to also get HST supporting data as part of the same call.

GSMTs. By the time JWST launches, we will know the outcome of the 25+m ground based telescope development and we will have natural targets for collaboration.
