Can somebody invite me to T-shirt & Dog/Travel Group Boards?

Hi, I create an e-commerce stores and I am looking for a way to get in a group boards.
My general niche is funny travel t-shirts, but I have another niche with dog t-shirts.

I would be happy if someone can invite me in order to collaborate.

I will pin in the groups with my personal account for safety reasons.

Regards,
Manol.
