Forum time-out

When I compose a mail here that takes some time, because of cutting sourcecode, tagging, making clear what I mean etc. it often happens that when I'm ready my session has expired. I then have to cut the text, refresh the page, make a new post and then paste the text again. Maybe the time-out could be extended to - say - 30 minutes?

I agree this can be annoying. We'll investigate if this time can be increased.
