What is involved, you ask?
- Brainstorm/collect a list of candidate publications for press releases.
- Post the lead time and submission requirements for each to the wiki.
- Develop or work with others to develop a (textual) press release layout.
- At the appropriate time (e.g. when certain details are settled such as keynote speakers), actually submit the press release.
That's it! It really shouldn't take a lot of time; a bit of surfing, perhaps a few email queries.
