I guess we have two different hwy clans...

sobe, diamond, cell and me are in one, the other has prudouche, metal and shoe.

Can we join more then one?

There should only be one Hwy.
Purdune set up the hwy clan in division 2 .
If you join it then we just change commander.
The one we are using has  a higher level

All Div 2 players the hwy that Purdune entered is much higher and you have to dissolve the other one to join that one.
Stitch if you quit to one you are in , I can send the invite to you after joining Purdune's we will change you to clan commander for the one we are using.
