Tier 1 is anything from 5-10 dollars, you get the blue italicized name and access to the forum with extra styles to test (nothing special, trust me).
Tier 2 is 10-15 dollars, you get all the profile privileges, extra space in your PM box, and you can make a blog.
Tier 3 is 15-20 dollars, you get a larger avatar (150x150) and access to the VIP Forum.
Tier 4 is 20-25 dollars and you get even more PM space.
Tier 5 is 25 dollars or more and you get a Pokecommunity email.
There is a tier 6 but it's not mentioned on the donations page and there's nothing special about it, I'm not sure how much you need to donate for it haha.
As far as becoming a mod, the FAQ says it better than I do:
Moderators are reviewed and selected by the higher staff. As with many forums, the general rule of thumb is "do not ask to be a mod or you will not become one." Anyway, moderators are chosen for their assets to the forum. If you would like to be a potential candidate, be sure to be kind, helpful, and make smart, quality posts. Don't spam and respect all those around you. When a moderator is needed in one of the areas you are constantly active in, you may be asked.
A moderator's job includes, but is not limited to, moving and closing threads, as well as editing any inappropriate ones. There is, however, much more to it than that. You must be mature and non-biased at all times and you cannot let your feelings on a certain topic influence your judgment. You must be fair to every member, no matter who, and it can even become a chore to come on each day whether you want to or not. It really can be quite stressful, so be sure you can handle this before you aspire to be one right away.
hey, I just have a quick question
I was wondering about donations and their privileges. My main question is how much I would have to donate to be able to customize my background picture, but Im also curious if there are any other benefits that come from donations.
also, just out of curiosity, how do you become a mod?
thanks so much
