We still have some free parcels open and 8 days still left to build. Tell your friends and get your own if you don't have one already!

Here is how to get started (we apologize for the multiple steps, but these have become necessary in light of recent grid attacks):

Step 1: Go to to get a ticket as an exhibitor or as a merchant if you want to sell your products. This is how we get your email address

Step 2: You will receive an email invite to create an optional local avatar account on OSFest Grid. You may skip this step and proceed directly to Step 3 if you would like to use your HG avatar instead, but you will need to contact us in Discord to set up a meeting with your HG avatar on the OSFest Grid.

Step 3: Sign up for an open parcel at

Step 4: We will get an email about your choice, then arrange to send a group invite to your local OSFest avatar as officer to your parcel so that you can build on it
