Hi and welcome to the One Piece Encyclopedia! Thanks for your edit to the User talk:Mugiwara Franky page.
With files do you mean images? You can add images freely as long as they have an appropriate point. For more info, check our Image guidelines. For deleting stuff, that only can be done by admins.Mugiwara Franky 09:38, August 20, 2010 (UTC)
No I'm not the captain, I'm an admin. Admins are select editors who are given special capabilities to facilitate the wikia. These include protecting pages, blocking vandals, and etc. Don't be overwhelmed though, while I may be able to do these things I'm just a regular contributor as anyone else here.Mugiwara Franky 07:30, August 25, 2010 (UTC)
There is an option to disable comments when you create a blog. I think the only thing you can do is ask the blog owner to change the blog properties. Kdom 10:54, August 26, 2010 (UTC)
