When I am clicking at other user profiles i can see collection info sorted by name, showing current amount of cards in my collection, like
Mia 1/4
Leya 3/12
Why there is no such info for myself, or there is, but i missed it somehow?

Ideally if such page allowed to click on model's page and redirecting to her page afterwards

If you see your name in the forum (except the 'answer this topic' location), you can click your username or avatar. There you will see the same visible (public) profile.

Click your name as above seen and you will see.

click your username or avatar

it would be more convenient to have it at your own account menu rather than searching forum for your posts, especially if you have no ones, wouldnt you agree?!

If one has not posted in a while and finding one's username is not easy, then do this:
@Brevado

Type in your username following the @ in the text box at the bottom of any page of any open topic. Then, click 'preview'. No need to save the post.

The number sign (@) followed by user name (no blank).
(this does not work for a user name with an underline {_}.)

This question has been asked many times over the years.

I have no idea why Totem have not made accessing your own collection summary a simple and obvious operation.

Hopefully it will feature in the new version of the program that Totem ahve said i in development.
