Good advice.
Make sure people feel welcome, cared about, not an inconvenience, not potential converts, (IE welcome even if they have no interest in converting right now/at all) not asked for money. They are people first. Not potential Sunday school teachers.
I'm disabled and have disabled children. At some places we are seen as a problem to solve, an inconvenience, ignored by most, despite a few people trying, if the majority outnumber those that try, especially the leaders who couldn't care less if you came, don't offer any support, (such as a place you can see, or a space where kids are less of a worry) then a few who try don't make much difference. Don't do token inclusion.
Community. If you are looking after your own congregation, they are going to tell others how good they are at caring etc. my friend moved church and I want to follow her as they sound so good. A community that care for each other and will include new comers in the same way.
Don't have an us and them culture. There will be people who are more in the know, leaders, more involved, but try to include everyone and make everyone feel important and having something to offer. (Ideas, opinions etc)
A structure that will include everyone. Don't set it up in a way that only couples can participate fully, or only those who are home in the day, or only those without children, or only those with plenty of disposable income, or only the able bodied. Eg small groups don't all happen at the same day/time.
Don't gossip about people.
Not cliquey. No set pews or seats unless for disability reasons. Don't stick those who can't stand at the back where they can't see the screen.
Don't have favourites. It's obvious who they are if you do. Don't use the same people as examples. Use generic examples, or anonymised examples.
Lots of social activities of various types. Meals, (have enough for everyone, allergies, etc) quizzes, walks, games nights, crafts, etc. Things you can bring friends to without having to commit to the whole God thing.
Explain what is going on or how you do communion, or which page you are on, etc.
Have photos and clear times, dates, service structure and expectations (Sunday best or casual?) on the website so people can check it out first. Good signage. Accessible building, well lit, but not too bright not too loud but loud enough to hear etc.
