Saw your edit summary re: removing the image wanted banner, and no, you did the right thing. If the request has been filled since the banner was placed then feel free to remove it.
Now if you disagree with a request that someone else has made or think its unnecessary, thats when you might go to the talk page first.
For example, on waterskip the removed questions come up fairly often in RW communities, so they make sense to answer specifically even if the answer is "no" because a user can't necessarily the difference between "not a thing so not covered" and "wiki is incomplete".
Anyway, just wanted to touch base. You're absolutely killing it lately, so its about time I said hi anyway. Im one of the mods around here, so feel free to hmu if you have any issues.
