I believe we're nearing completion on this. This turned out to be slightly more challenging (from an administration level), than we both originally thought I think.
However, I think what we're going to do is just have each blog have its own keywords designated by administrators only. Greg and I spoke at length about this, and development for this is almost completed. I have two main functions left, which I hope to finish soon.
I finished one of the two functions on Friday. I'm now working on the visible portion (or search). I expect to have this done either today or tomorrow. We've been very busy on our end with this whole "Reboot" business.
Great. Let's review tomorrow what has been done on the backend/admin... in addition to the search feature.
Yes, we are hoping to have a functioning portal and site admin implemented by Friday -- so we can begin to play with it fully from a user and administrator standpoint.
