Though that's a good suggestion,
We've decided as a group that we don't want to give donators any types of "special privileges" for multiple reasons.
1. This is the main reason in my eyes. When you're donating to a server, you're not supposed to get anything in return. Think about it, donating to the Red Cross, is a really vague example. Occasionally they'll send you a packet of coupons, but for the most part, you'll just get a pamphlet that says thank you. For now, that pamphlet is the Donator rank on the forums.
2. Donating and receiving something in return would be a big red flag for a certain company. With the donation money, none of the developers are paid. ALL PROCEEDS go to the server directly (VPS hosting, website hosting, etc.) AllGoFree is more or less a not for profit organization.
3. Donator only items just ruin the fun. We want to have a legitimate RS Remake, the more 'little' things we start throwing in, the less like RS it is.
Thanks for understanding! :-)
