There's two answers: what 당신 can do, and what 당신 should do.
당신 CAN ask to have the logo and banner changed to any club at any time, regardless of activity, and the staff may oblige you. This is considered troll behavior pretty much universally, however.
This has been discussed a fair amount in
link. It's not universal, but the general feeling is that 당신 SHOULD do something like this:
1. 당신 make the 아이콘 and/or banner.
2. 당신 post it in the image section.
3. 당신 start a message thread in the forum, for discussing the change. In that 포럼 thread, 당신 also point to #4 & #5, below.
4. 당신 post a pick with an end date, asking users to vote to keep the original 아이콘 또는 to change to the new one.
5. 당신 post a pick with an end date, asking users to vote to keep the original banner 또는 to change to the new one.
Note: the end 날짜 should be long enough to allow for enough 팬 to respond, but not ongoing. 2-4 weeks is probably good.
6. If the users vote to make a change to the 아이콘 and/or banner, send a message to the staff (using the "contact us" feature) with:
a) the name of the club
b) the URL(s) of the completed picks, showing that users wanted the change
c) the 주소 of the new icon
d) the 주소 of the new banner
7) The staff makes the change.
