Saw somebody else’s goal and clicked “I’ve done this”. Later went to make an entry. No problem. But I don’t have a link to “write an[other] entry about this”. My only options are to edit my existing entry or to reply to that entry.

Maybe this is by design, so that posts from people who have already done goals don’t overwhelm posts from those who want to do them. But this does make it a bit harder for people who have previously accomplished a goal to convey some of what they learned in the process.
