I just mailed tomboy-list to let everybody know that I won't be around to help much this release cycle (stupid real world!). The big bummer here is that I won't be able to work on automatic background synchronization, which Tomboy really needs to bring sync to the level of AWESOME.
So, as I said in my email, if you've been waiting for the perfect moment to dive in and be a free software hero, then now is your chance. Mess with the wiki page I linked above, send in patches, draw mockups...do whatever it is that you do so well! I'll help by reviewing patches and doing whatever polish/integration work I can do in January before the UI/string freezes.
Oh, and keep in mind that we're still looking for a hero to revamp our tagging UI, too.
With your help, Tomboy sync in 0.10.0 will be legen-
...wait for it...
