When posting a new topic in Google Groups, I made a few misleading typos that I wanted to correct, but I couldn't find a way to edit the post. Is it possible to edit a post in Google Groups (in case I need to correct something in the post?)
Once the message is posted it cannot be edited. https://groups.google.com/forum/?fromgroups=#!topic/gmail-generation/7W51BDOBWIg
(Desktop in 2018) When viewing the post, in the upper right corner is a Reply button with a pull-down arrow for More Message Options.
Note: You'll see this option only if you are among the Select Groups Of Users allowed to Edit Others' Posts in Moderation Permissions (see a previous answer above for how to change that).
Pull down More Message Options and choose Edit.
You'll see a text link to Edit Subject.
