Surely you can appreciate the irony?
You want us to share with you how to do something, though you don't want to share your script with others, who might want to learn something from you.
mIRC scripts are open source, and I'm very glad it's like that. One of the best ways to learn to script is by looking at good examples. I'm pretty sure you've also looked at some code here and there, as everyone does. Wanting to hide your code from others is extremely selfish, and ungrateful.
Besides, what makes you so sure people are going to want to "rip" your code? Do you really consider yourself as an extraordinary scripter, who uses scripting concepts that are unknown to the scripting community, introducing innovative techniques that would revolutionize the way we script, if they are revealed?
Chances are anything you've made has been done thousands of times before, and will continue to be redone thousands of times in the future.
To conclude, if you don't want people to see your code, then don't release your script. It's as simple as that.
