The issue with previewing is fixed now.
This is probably a silly question, but can one be both a Copper Member and a Donator?
Short answer: Yes, mostly.
Long answer: Each forum user belongs to several groups in three categories: one primary group, one post group, and any number of additional groups. Your group membership looks like this:
Primary group: Donator
Post group: Legendary
Additional groups: (none)
A typical newbie's membership looks like this:
Primary group: Regular member
Post group: Newbie
Additional groups: (none)
By paying the fee and then visiting the paid-promotion page, you get the Copper Member and Whitelisted groups added to your additional groups section. (The Whitelisted group is what gives the reduction in time-between-posts.) So the two examples above become:
RaizePrimary group: Donator
Post group: Legendary
Additional groups: Copper Member, Whitelisted
Example newbiePrimary group: Regular member
Post group: Newbie
Additional groups: Copper Member, Whitelisted
Once you're in the Copper Member group, the promotion page gives you the option of "wearing" that membership. I posted a screenshot of this before. Once the example newbie does this, their group membership looks like this:
Primary group: Copper Member
Post group: Newbie
Additional groups: Whitelisted
(And using the same form, you can revert to the previous state.)
However, if your primary group is manually granted, such as Staff or Donator, then you will get an error when you try to do the above operation. It's not allowed to go from a manually-granted primary group to an automatically-granted primary group automatically. If for some reason someone wanted to wear Copper Member instead of Donator or whatever, they could contact an admin and we would probably do it. But it would be purely be an aesthetic thing: any additional privileges a non-newbie would get (I think there are none) are granted just by having the group in your additional groups. (
Newbies need to have Copper Member as their primary group to escape the image restrictions, though. That only looks at your primary group and post group.)
