You might wait for any testers/comments. If I get around to it I might. There ARE others here that do website stuff (I have a minimal personal one).
You might put a Topic(s) also in the -
BUT you might contact an Administrator, Moderator, or Developer to see if its appropriate since it is a "tool". Look at the bottom of the main Board page and simply click on any of those (color-coded) and ask.
Otherwise, sit tight and see if it gets noticed. You probably have a better chance of it being seen here as to Neowin. I believe the oldies here are more "geekie".
As far as "spammy", it's all good AFAICT. You might also read the rules to acquaint yourself with them (link at top of every page).
As long as you software (noting you have other) is "free" and you make no attempt to "sell" a product, service, etc, you're fine ALTHOUGH you may discuss it but do NOT attempt promotions (search for posts by member "rloew" as examples). We are quite strict about our rules.
Welcome to MSFN! And I hope that we can help you out in any of your endeavors (we have a few coders here too).
