Welcome. You should receive a welcome message that highlights a few things. In this community you are free and independent. Do exactly what you would do if you just moved into a new home: look around and make yourself comfortable. Update your profile and create your own space to reflect who you are. Meet other people, check out discussions, groups and activities. Read and learn.
If you don’t see anything that you like, then create something. Depending on what you want to create, you may have to wait a little for your “trust level” to go up first.
Whenever you are ready to sign up for different things, then go ahead and sign up. From time to time you will receive opportunities posted in community spaces or directly from the UPG Foundation. You can always choose to opt in if you want.
