rb-j, that seems to be standard operating procedure for all Stack Exchange sites. See this answer for why you may not be able to edit a question:
There are a handful of conditions where we will stop accepting suggested edits:
- A large number of suggested edits by you were rejected in the past week (at least 5 more than one-third of your accepted edits).
- We are out of empty slots in the queue (40, with several exceptions. See here for details)
- There is an edit to a particular post that was not approved yet.
- You are not logged in and the post is less than 10 minutes old.
- You are on a child meta.
In the past no "edit" link would be shown at all; since July 2012 the edit link is disabled and the mouse hover tooltip will explain why an edit cannot be suggested, like "Account is not allowed to suggest edits".
edit from r b-j:
this doesn't make sense. see, i can just edit this now and the change take place instantly, because i have enough rep to do so.
but if someone with insufficient rep tried to edit this, it goes into the queue, but that prevents me from editing. that should be unrelated.
