A couple of questions for Admin

[Kollba]

I tried a few minutes a go to send an answer to a private message but nothing happened.
Should I not be able to see my answer right under the original message just like it shows up in the threads ?
And I looked in my outbox - empty.
So I guess my answers went right out in cyberspace or...?

And the second question. It happens all the time that I get time out and have to log back in. It is rather annoying when I am writing something in a thread and want to check something on another site or just visit the bathroom. When I come back I have to log in again.
Isn't it possible to change the timeout to at least 30 minutes ?
