SLRC and Ouachita use EE.net, Acadiana does not. For the last Acadiana trial, EE.net did a complementary on-line entry and mailed it to Acadiana a week before the deadline for entries. Nor sure if he will do it for the 3DQ. You can find the FTS for Acadiana on working-retriever.com and get them to mail you an entry.
I recently made some phone calls asking those same questions, should know more next week.
Rich, i got your email and will get back to you shortly.
Either way, EE will be taking online entries for all of the events. Hopefully they will be EE events, but if not you'll still be able to enter online. The event will just close a few days earlier on EE.
