hiya...
Wow, I never expected anyone would still be using these themes, in fact I had completely forgotten about them. I think they will "just work" with RC3 or if there were changes they were minor.
I will look into repackaging them for SMF RC3
I have also made some new colour variations for my own site, so if I have a free minute I shall package those as well.
Thanks for pointing out the problem with the calendar. It's not a feature I use very often, so it appears I just forgot to check how that would display. Silly me.
