Is there a possibility to see wagn version within the Wagn after the login?

Yes!

The *version card is a card like any other and can have its permissions set as desired.  In fact, most wagns have a custom rule to make it public, so on a Wagn with restrictive default *read permissions, all you would have to do is delete that rule.

Note that the default layout has something like this:

Wheeled by [[http://www.wagn.org|Wagn]] v. {{*version}}

Changing the permission for *version would leave you with something that looks very partial, like

Wheeled by Wagn v.

So you could:

• put all of that into a card and restrict it, or
• take away the "v.", or
• just take it off the layout altogether
