I've decided to hire a new admin to help with tag maintenance duties, since the other two admins are fairly inactive and the new approval process is a lot more intensive.
The main privilege admins have over moderators is the authority to approve/delete aliases and implications. jxh2154 has been a long time contributor here and has displayed good judgement in the past, so I have no reservations about taking him on as a new admin.
I'll continue to look through new requests and approve ones that have received a fair amount of discussion. Please do use the Tag Alias/Tag Implication headers since it makes them easier to find.
