Thanks all for the responses here. All have been incredibly helpful! Some very good advice.
My son has continued to receive some emails and these suggestions are really helping us get a broader sense on "what to look for" in the responses/communication (though I realize it's early still).
Most are simply thanking him for his email, passing along ID camp info, and either asking for his game schedule or simply saying to stay in touch. I'm guessing that most are not focused on sophomores (class of 2025) too much right now, but I could be wrong. I'm curious at what point the process picks up (early junior year/mid-way through after the fall season, etc.)?
Thanks again!
