I tried editing a post that I was able to edit after I first posted it but now the "edit" feature is no longer there. Any help?

You just have to change the url of your post.

first part should be http://www.fantasyflightgames.com/edge_foros_editar.asp?efid=

Can I Facebook Like "these forums are lame" ?

I think the Edit function is only active for a certain amount of time after the initial post.

The edit BUTTON is only available for a bit. You can get around it with url manipulation.
