You have been caught in one of the anti-spam measures. You will get editing rights after a certain length of time on MobileRead.

I have just changed your user status to give you access to Private Messages. I'm not sure whether this also helps with editing access.

If you still can't edit the post, report the post (The button), and in the report say how you want it changed, and a moderator will edit it for you.
