You aren't taking over if you're one of a handful of people sharing. I'd rather see more from the same person than nothing from nobody.
Mild is mild. Pictures of you looking cute are definitely welcome. Some people use gonemild the same as wild, you know, minus the actual nudity. Really, it's about what you're comfortable with sharing. Tease us (please) or don't tease us - it's up to you! 😁
I say yes to 2-4. All of those. 5 isn't a bad idea, but maybe this isn't quite the right community for it?
If, for whatever reason, you don't feel comfortable posting as often as you have been, then don't. No matter how popular your pictures might be, you have no obligation to share anything more than what you want to share. On the other hand, if you do want to keep posting this frequently, then don't worry about taking over! Flood the front page with pictures of you in, I dunno, just plain PJs or something, if that's how much you want to post. If you end up being 95% of all the posts in here, that doesn't mean you're posting too much; it means everyone else isn't posting enough to keep up!
