Hello Bas, welcome!
Here is the other bird topical forum to also post in:
Birds Perched, Birds Flying, Birds agroundhttp://goscf.com/t/5934
You have some nice stamps and cancels, birds are a favorite of mine, and cancels too, although I do not collect birds specifically.
I noticed in another forum you mentioned about emails through the forum. You will have access to the forum email system and also trading, buying and selling from members when you reach 50 posts and have two weeks in. Rules are the button on top right.
Also remember to visit the Introduce Yourself forum and start a thread to say Hi to the members and say a bit about yourself.
