Editing?

[Torchwatch]

Even after you have posted an item you can edit it (until someone else posts on the thread), this is your chance to test and repair links etc.
A correction is better than permanently posting a failed link then a series of 2nd, 3rd and fourth attempts.
Don't type urls, it never works right first time, copy and paste them, it is quicker, more accurate and if the link fails it is due to computer error not yours.

This bit added in Edit mode for no apparent reason.
