Here is what I would tell any new RF100 coordinator, based upon 4 years of work (8 person years) for my wife and my focus on the clean Energy future for Middletown, NJ:

• success is more likely in  democratic towns with democratic mayors, and democratic committee/council; greater resident leverage is possible in a town founded under the "Faulkner" style of government;
• much greater probability of getting successful renewable bids if the town is in PSEG electric territory (because residential rates are > 2 cents/kwh higher in PSEG compared to NJNG electric rates (renewable electric vendors find it easier to bid lower than PSEG electric rates)
• I suspect, but have not to prove that a town which previously declared "we are still in" or signed a clean energy pledge, is more likely to engage in  RF100.

 We created our own organization, "Middletown for Clean Energy", organized a large rally and march, and recruited a large team.  300 Middletown residents signed a petition for a clean energy future

In Middletown's present form of government, 11,000 signatures are required to force the Middletown Committee to take action ,

160 people are currently on our "Middletown for Clean Energy" email list- I send roughly 1 email/month on average.  I also have a larger list of interested residents in towns throughout towns in Monmouth County.   We write and/or talk frequently to the Middletown Green Team (my wife is a member), the Mayor and elected Committee, and various town officials. We communicate frequently with various managers of Sustainable Jersey, and frequently attend Sustainable Jersey events. We give motivating talks to Green Teams in various towns in our county and other counties throughout NJ..  As a result, we currently have germination of a nearby 8-city R_GEA .  This R-GEA will be hosted by Red Bank, and provide renewable electricity for all towns surrounding  Middletown.
Among Middletown positive steps:

• The Middletown Mayor and Administrator were interested and requested an R-GEA briefing (Pat and I hosted).  Then, the Sustainable Jersey "Community Engagement" hosted a meeting of all interested monmouth County mayors/administrators)
•  Switched all its ~80 municipal electrical accounts to a 2 year contract for renewable electricity, eff 6/2020 (AND SAVED 10% on the electric bill)
• Contracted for construction of highly efficient (high LEED score) municipal building- with solar on roof, and multiple EV chargers in parking
• submitted (on Feb 4, 2021) Community Solar proposal for a large canopy solar over the train station parking
• Both Mayor and Town Administrator stated (on April 5, 2021) our team's Middletown Energy Plan will be incorporated into the Middletown Master Plan (currently under revision).  The Middletown Energy Plan is based upon the 2019 NJ Energy Master Plan, and lays out the path to ~38% GHG reduction by 2030 (enhanced federal support is estimated to result in 50% reduction by 2030), and 90+% GHG reduction by 2050.  RF100 (where the town contracts for renewable electricity for all its residents) provides the greatest emission reduction by 2030. However, the plan requires many other Actions to reduce emissions to desired 2030 and 2050 levels. These Actions align closely with Sustainable Jersey "Gold Star In Energy" Green Team Actions.
