There's two answers: what anda can do, and what anda should do.
anda 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 anda SHOULD do something like this:
1. anda make the icon and/or banner.
2. anda post it in the image section.
3. anda start a message thread in the forum, for discussing the change. In that forum thread, anda also point to #4 & #5, below.
4. anda post a pick with an end date, asking users to vote to keep the original icon atau to change to the new one.
5. anda post a pick with an end date, asking users to vote to keep the original banner atau to change to the new one.
Note: the end tanggal should be long enough to allow for enough fan to respond, but not ongoing. 2-4 weeks is probably good.
6. If the users vote to make a change to the icon 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, tampilkan that users wanted the change
c) the link of the new icon
d) the link of the new banner
7) The staff makes the change.
