Just to keep everyone in the loop, after a small review of our settings, we’ve decided to bump wiki-editing to TL2 here on meta. 
For most, this will likely pass without notice but it is something to be aware of when suggesting people jump in and make direct edits to any docs (for instance).
For anyone who wants to suggest an edit to a wiki who isn’t yet at TL2 just leave a post in the topic as normal and we can help you out.
