Hi!
It would be interesting to see what changes/updates that you are working at atm, and also some sort of timeframe.
A feature that have been requested many times would an "updates" page, where you could write what updates that you guys working at right now, and plan to do in the future. This way we could check that page first before suggesting features here, since a lot of the bugreports etc reported here are stuff that someone else already has pointed out.
It wouldn't have to be anything fancy, just something like:
Within 2 weeks:
*Adding the ability to write your own example sentences.
*Adding a word search feature for vocab lists.
Within 1 month:
*Making skritter an addon for firefox
*Adding support for Playstation3
Within a year:
*Making skritter the only viable way of studying Chinese.
In the future:
*World domination
etc etc
This would take skritter.com to a whole new level, making it even more professional. It would also make us users more happy, looking forward to the pending changes. And it would save you the time of answering requests that you've already answered 10 times before.
