I've finally completed the tag list for the comm. It's by no means entirely comprehensive, but I think it contains most of the applicable tags that people will use.
If you are a community member, you can tag any post in this community by clicking on the edit tag button for each post. If you think a post wasn't tagged (or perhaps also needed to be tagged with another tag), feel free to go in and tag it properly. We're hoping that tags will help everybody find things more quickly, and it, along with the memories, should be helpful for people who need to find things in this community.
Please make a note if you think there is a tag I should add, and we'll see if one is needed or if there's a tag that's applicable or if a new one should be created.
