Forum session timer is too short

I understand that the session timer was greatly reduced in order to mitigate spamming runs. However, I feel that it is really too short. For example, I was in the middle of drafting a post, and when I came back, the whole thing was lost because I hadn’t saved it as a draft before the session timer logged me out without warning.

Is there any way we could get this increased? Or, at the very least, have some notification that we are about to be logged out [while editing a message].

Indeed, I would also like longer session times. I have often found myself looking at VexForum between classes and having to log in again every time. Would at least 1-2 hour session time be harmful for some reason?
