Recurring posts might help. They also nail down your main topics so folks know what your blog is mostly about.

getting_started and reddit_refugees are good for newcomers. fandomcalendar is a place to find events. Also watch for communities that post multiple events, like allbingo (a new fest each month) or smallfandomfest (events for different small fandoms).

That's an excellent plan.

You can also subscribe to communities and their posts will appear on your Reading page. Use the Interests page, followfriday, or dw_community_promo to find ones you might like.

>> Still too new to know exactly what <<

Look at other people's sticky posts or profile page to see what kinds of things they are saying. It'll give you an idea of your options. A blanket statement or transformative works statement is about how other folks can use their fanworks. Some people post a friending policy. You don't have to set a stance immediately, you can think about possibilities until you decide what you want.

For meta, consider meta_warehouse and marchmetamatterschallenge.
