This a 4 fold question/issues

Before going live in 2-3 weeks I've create today a new domain that will serve my users as a blog and a forum.

Before continuing any further with setups and contents I must resolve few issue that I'm sure will hunt me in the future and I need to set it straight from beginning.

On a virgin install, the first forum is named "main-forum"

I've changed it to the word "welcome" in Hebrew but at the navigation bar nothing changed and it is still showing "/main-forum/"

And yes, I know that I can delete it and recreate, this is fine as long as I do not have any content in it, but once there is I cannot delete because the content will fly to the garbage…therefore a change of forum name requires a change in the URL as well.

That was point 1&2 (red & green)

Point 3. (blue) Seems to be incorrect count of forums. Looks like you're counting categories & forums. This is also was observed in my test site.

Point 4, (yellow) is there a way to eliminate the page name to avoid redundancy or to assign a description like "Welcome to my Forum" bla bla?

Thnak you
