The last thing I will say is I don't quite get why me removing my gallery is ruining anyone's life. Quite frankly my skins were not all that great and I seriously doubt many people use them on a continual basis
Let me try to explain that one, JC.
No, you are not ruining anyone's life, but you are *taking back* something which you created and previously shared with the world. Those skins you did are unique. When you remove them you are not doing anything bad per se (you created them, you have the right to remove them at any time) but you are preventing countless other people from enjoying them in the future. Personally, I think that is a total waste of creative energy, and I'm sad when something like that happens.
Now, in terms of Sysmetrix, the application itself, you are indeed hurting it, by removing choice. Then again, Nick hasn't been paying much attention to it either, but the proof that he made an excellent application is that many people *still use it* after all this time.
Oh really, What friends? Are you really my friend?
For someone who has 'no friends' here, as you claim, you sure had a lot of responses in this thread, all of them supportive of you. If they didn't care about you, one way or another, then this would have been a very short thread indeed, isn't it?
One thing I learned in life is that friendship is not black and white. It's made of many tones of gray. Furthermore, friendships are not static, they grow (or shrink) over time - so do not discard so easily the possibility of one day having a beer and pouring your heart out to one or more of the regulars here. Who knows? 
They are only skins and your life is not going to be destroyed ( or even bettrer) because someone removes them.
They are much more than 'only skins', and it saddens me you can't see that. Each of those skins you created has a bit of *you* in them.
But this isn't really about skins. It's about you undoing what you did and getting your ass back in here. You already recognized that you might have jumped the gun (you did, and you know it, lol). Personally, and I'm sure all your friends here will agree, I think the better man is not the one who makes a decision and then sticks to it no matter what, out of pride and fear of losing face, but the one who is humble enough to backtrack when he recognizes he made a mistake. Unlike the former, the latter takes some real strength.
So, up to you now.
