From now on, ANY MEMBER can edit his/her posts for up to 5 minutes afterward. That time limit (5 minutes) is negotiable -- we shall see how it goes.
The idea is simple: WET CEMENT. Think of your posts as being made of freshly poured cement. You can only "work" the cement for a limited length of time.
When you make a post, you will notice in the upper-right corner a dark button, "edit", the color of wet cement. After 1 minute, it will turn a bit lighter (if you refresh the page). After another minute, it will turn even lighter grey. The last stage is a very light grey button. After that, the button disappears.
Right now, you have 5 minutes from the time you first make your post to make any changes.
If you get in at the last minute, you have about 5 minutes to click "submit" after your changes are made.
The timer keeps going until you click "Submit" after your changes are made! If you exceed 10 minutes from when the post was first created, it tells you, "Sorry, that post can't be edited anymore. The cement has already dried."
As I said before, if 5 minutes is too quick, we can try something longer. I just want posts to be stable -- made of cement -- rather than made of silly putty (for those of you who remember what that is)
