Don’t be shy!
Introduce yourself with a big hello! Senior members should welcome new members with a friendly greeting. Remember to ask your fellow creators what’s new and amazing on their channels. They’ll be sure to tell you. If you show an interest in someone else’s channel, it’s likely they’ll show an interest in yours. When you do that with enough people, you’ll be amazed at how quickly your views and subscribers increase.
And be nice :)
Please be polite, respectful and positive in the community forums. It's also good etiquette to subscribe to the channels (within reason, of course) of other people in your community.
This is YOUR community. Make it great!
