How to edit a post on this forum

How does one edit a post on this forum?

As a "normal/standard member" you only have a very limited amount of time to "self edit your posts (From memory I think it's an hour.). One of the benefits that comes with being a "contributing member" is having no time limit on when you are able to "self edit" your posts. Any member can become a "contributing member" simply by meeting the criteria of "contributing".

thank you for the information.

Is the same thing true regarding "for sale" ads? If I place an ad on Milsurps does it get similarly frozen?
