Have you joined the mailing list yet? I'm getting your messages but have
to approve them through the admin. If you could join, we'd love to have you.
I'm glad you're testing the development version for me, this is very useful.
Concerning the bugs you found:
Bug1: I knew about this bug and had fixed it at home but forgot to
commit, it's commited now to github.
Bug2: Also knew about this bug, fix is committed to github.
If you could pull the latest changes from github and test these changes
out for me that would be really helpful.
Thanks a lot for reporting these bugs and please don't hesitate to let
me know about other issues you find.
