The time allowed to edit a post is way (repeat WAY) too short. Folks should have at least 30-60 minutes to edit their posts...(or even better - no time limit at all). I've timed out at least 20 times when adding details or corrections to posts shortly after posting - which is pretty frustrating.
The current time limit is far too short for folks to do simple stuff like a few google searches for more details, or to check routes on mapquest, etc.... etc... It's an impediment to getting more/better infomation into our posts.
Let's update this to something that's more usable please. If you feel you must have some limit (for whatever reason..?...) I'd suggest 60 minutes - and put a note in the footer of the posting window so people know what the limit is.
