INAP will be officially updated by the end of the week. I am currently running final tests on this version. Most known bugs have been fixed, the Admin panel has been re-written to be easier and less confusing, and many features critical to the success of this plugin have been added. (A omplete list can be found on the INAP page.)
If you would like to help me test or would like a sneak peak, the current developmental release is available here please read the INAP readme for installation instructions.
Please report any bugs found to this post or the main INAP thread, and ensure you mention that you are using the developmental release.
