Don't slave over the perfect response, hit post, and watch it disappear because you've taken so long to write it up. Protect it instead.

Option #1: If you've taken a long time to write a post, select the entry and copy it before sending it in. Keyboard commands are quite efficient for this purpose.

Ctrl+A or Command +A (select all) and then Ctrl+C or Command + C (copy)

If you've timed out, just log in again, reopen the place where you'd like to make your post, then paste your saved post & send it along.

Ctrl + V or Command + V (paste)

Option #2: Compose your post in your favorite text editor or word processing program and paste it over from there after you've crafted the perfect entry.
