Couple of tips:

• The first line of your post becomes the title of the post over here on Lemmy.
• So maybe avoid putting the lemmy community/group in the first line (it looks weird here). You can put it anywhere.
• Make sure that if you're "@"-ing others, you put the lemmy group/community first. This is because Lemmy prevents spam by allowing people to only post to one group/community at a time and so only heeds the first. Mastodon, and other platforms don't do that so you can safely "@" others from other platforms and they'll get notified.

Also ... hi from Lemmy!
