@Sadr,
You are correct in thinking that I have not finished the 1.1 version for SMF 2 Beta, I am currently working on it. It shouldn't take me too long because it will be very similar to the SMF 1.1.5 one, and the main changes were not to do with db queries to I can probably just copy chunks of code to do it relatively quickly. I hope to have it done today or tommorrow so that I can think about finishing another mod.

To upgrade between versions, you will be able to uninstall the old one and then install the new one, the package manager should give you an option not to delete the data that is stored.
@nopity4u,
Sounds good. The trick to an open-ended mod like this, is to be as inventive as possible with the functionality that it has. I have tried to add more with the template functions to make it easier to customize.
@Lady Night Owl,
It would appear to me that that is not the correct line because there is nothing wrond with it. Its possible that the internal error checking in SMF 1.1.5 could be making a mistake due to some iterations or something, I've had it happen before. Could you please post that entire file so I can have a better look at it?
Edit:
Sorry I didn't get around to documenting the new features yet, I will try to do that tonight.
