By the way do we have a option for Securing our Mod with a password?
So not everyone can open the file and fool around with ur hard work and then puplish as their own
Well, taking the NWN modding community - which is huge and persistent - as a possible model, that sort of thing has only happened a couple of times in 12 years.
Generally it's been stepped on hard by community feedback and site administrators, and has neither become a trend or a recurring problem. Known offenders get short shrift from everyone else. Other modders have taken their ball and gone home, and the decision to withdraw their work from circulation has generally been respected by the community.
Admittedly, that is non-monetized mods, and was in the Days Before Kickstarter In a Smaller Internet, so things may be different - especially if mods are a source of income.
Should it happen, your released work and the release dates will still be readily available, so it should be trivial to prove. Depending on the distribution model(s) that evolve(s) and the money involved in a given case, I would expect most site owners would be disinclined to participate in someone else's theft.
Which said, you're already working with someone else's freeware. Charging for it seems to me like it should be something case by case that you specifically arrange with Larian before it happens. But I'm neither a lawyer or an entrepreneur, so what do I know?
