Since my comment was posted, you can now specify multiple topics in the first topic field. But you can still use the old method of using tags within your post.
My main point was, just post it once, instead of spamming 10 topics with the same duplicate content. So if you want it to show up in multiple topics either hashtag the other topics : #charity #ocean-whatever etc or put it in the top topic bar. :)
GOT IT. Tks.
Another question.. How can I change my login password?
Click the avatar in upper righthand corner, then PERMISSIONS, then the pencil icon.
