Give yourself a pat on the back for all the dedication you've put into this project. You're a real workhorse, but I think you're also kind of a masochist for beta testing all the mods and maintaining the subscription all by yourself.
I originally thought the whole point of 7thHeaven was so that modders could upload all the little tweaks and updates on the fly and those could then be hotfixed via individual subscriptions for each mod suite. I suppose anyone could write their own subscription on pastebin and maintain their own mega/gdrive/dropbox shared folder, but have you considered a second subscription list with a shared folder open to everyone contributing to the currently compatible mods so they could update them immediately? I guess it would be a lot more cluttered, messy, and glitchy than your current subscription layout, but it'd certainly reduce the burden of testing and updating. Maybe a tutorial for making mods compatible with 7thHeaven or making .iro a forum standard? This is the way a lot of modding communities are leaning. Frankly I think you're going to burn out converting and testing everything yourself.
Now that I've looked into it, anyone should be able to do all this right now. It's not like Iros hasn't explained everything already for slow people like me. Still unless the shared directory is owned/hosted/administrated by someone who's actively involved in the modding, then it could disappear at anytime.
