I could lead either or both of Intro to Omeka and Intro to Plugin Writing for Omeka if there are enough people who want to flex some PHP coding muscles.
Regarding the Intro to Omeka option, it’s fair for me to warn that I spend way more time writing the code for Omeka than actually using it in any sense, so if others appear who have experience using it, I’ll defer to them if they are also interested in leading that.
There’s another workshop/discussion possibility that I might be able to suggest. I want to get a few more ducks hippos in a row before I throw it out for sure, though. 😉
