That will be harder to manage. And I think an website like AdminAddict should only have one style I don't really like forums with more then one style it seems a little amateurish but that is only what i think.
Thanks for the suggestion - I'll discuss this with the team. While having a darker theme to compliment the existing lighter theme would be a viable option, this community has grown around the already existing custom theme.
Sorry to hear that... Chris M. said he'll present this to the administration, hopefully your suggestion will be implemented. Admin Addict pleases, I tell 'ya!
Our current theme is a custom one and I presume it would require an identical copy (but darker) be created (of course not gratis) so it isn't exactly something that can be done at the request of a single member. It may be a possibility, but I do not foresee it in the near future. However, as Chris said, the administration will be sure to review it.
I think what we have now, the one custom-made theme, is fine. A lot of people seem to like it, so I think it should last us to "AdminAddict 2.0" - the entire site revision that I'm sure we will see in the far future.
