Per a thread from 5 years ago, I noted that some people had gotten permission and if nothing else to contact the owner of Decision Games about permission for other titles. I emailed Chris "Doc" this morning and received a very prompt reply:
"...the exclusive license for HexWar to develop e-versions of our DG and SPI games expired over a decade ago. Now the only items excluded are the D-Day at Omaha Beach series, RAF series, War in Europe, and SGFE (because we developed and market e-versions of those games).
You’re welcome to submit your RCW module to DG or post elsewhere. We would hope you’d also convert the RCW edition we did in S&T magazine about 10 years ago so players could play either edition."
That indicates the wiki page needs to be edited to reflect this and the moderators be made aware of the change so that titles that have already been submitted can actually be hosted and future submissions (like mine) will be accepted.
I'm so new to this that I've hesitated editing the wiki note on Restrictions. I'm also unsure how to bring this to the moderators attention so that at the very least, they'll approve my game.

FYI, while searching here, I noted that some people couldn't find the link on the Decision Games site that provides a listing and downloads of game titles. Here you go:
