First off, I'm sorry I haven't been around to reply sooner than now. Like I said in my OP, I'm hardly ever here any more. I can't believe it's been almost two months!
There really isn't anything that's in any kind of urgent need. The only thing I ever did was keep my eyes open for trolls or spambots to make sure that they weren't disrupting the group here. If someone is disruptive, and a jury (as inconsistent as they are) can't or won't censor them, having a host that can block them from the forum can serve as a last line of defense. But in a year, this has never happened. As little activity as this group gets, I don't expect that to change.
There are other "super powers" that you will have as a host, and the host functionality is fairly straightforward and easy to understand. A list of those powers can be found here. After I post this reply, I will promote you to group host and retire myself. That will automatically make you the lead host of this group and you can then shape it as you see fit.
A benefit of being a group host is that you will have access to the "Forum & Group Hosts" topic forum. You should now see it as a red folder in the folder list on the left.
If you have any further questions, feel free to reply here or send me a PM. I will check in again in the next couple of weeks to see if there are any replies from you -- if not, I will assume no news is good news! 
Thanks again!
