Yes you can, each group is created by members, Now that ep changed format, I can’t find how to...I'll search for ya<br />
Updated answer:<br />
Be on your main page, click on group link. On upper window, there is a box with “I” in it. Type in the name of the group you want to create.<br />
If the group already exists, it will appear below the box window. If not, a window will pop up on your screen saying the group does not exist click on create
Yes...You can...But you draw the attention of your friends to join in it.
Neither can I...:(
Yes, just type in the experience name and if it pops up that no such group exists, start your own group. Used to be much easier before the "improvement", but it can be done.
I think that is exactly where the groups come from.
