1.) I completely agree with this suggestion. I constantly find myself clicking on the warning level percentage of other members to no avail. This would serve as a great help to one who is considering dealing with another member who has obtained a notable warning level.
2.) Personally, I don't feel that this is completely necessary. However, if other members see this as being a possible benefit, then I am all for it.
3.) I do agree that the double-rep problem should be fixed, but don't necessarily think that disabling/limiting rep for a certain day would benefit anyone.
4.) I completely agree with @Leader on this one. I too use FK while I am at school, and I would not enjoy turning around and seeing a teacher looking over my shoulder with porn accidentally popping up on my screen. I also feel that this would only work to make the site more 'low-quality' in a certain sense, as I know that I wouldn't think too greatly of any 'Gaming' forum if I saw porn on the site within the first 5 minutes of joining.
5.) I do not agree with this suggestion. I do understand the one and only rule that the Spamming & Trolling Section has, but I don't think it's necessary for any menber to throw around swear words, racial slurs, etc. at another member. If you take a look, you can see that the Spamming & Trolling Section already has enough vulgar content in it now, if you ask me.
6.) I agree with this suggestion 100%; in every aspect. Not much to say about this one.
7.) While I certainly do agree with this, I can see why other members would be concerned about their own personal items being targeted. Though, if that can somehow get sorted out, then I'm all for it.
