Derek, when would be an appropriate time to ask questions about a Gen Con 2020 event? Hope you have safe and trouble-free travels to Indy. :-)
Probably after this year's convention :) Ultimately, the answer depends on what your question is.
If it's fairly general, September is a fine time to drop a note. If it's specific, then November-January is probably a better timeline.
