Here are the "tips" I have learnt for using #Lemmy with #mastodon
Follow communities and people by copying the url into the mastodon search. You follow them a bit like you would a hashtag and then all posts from that community will show in your feed.
Reply to posts or comments you copy the url of a post or comments into the search on mastodon.
Post to a community by @ it in for example it would be @ "feddituk@feddit.uk" or @ "unitedkingdom@feddit.uk".
