When I get an email with a match result or telling that the free transfer went to another club. If I click it, I get to the RS login page. Same happens if I click on a link to a player from this forum.

and that was happening from the very start…on different pc’s and browsers

There are 3 scenarios:
1) you are already logged in and inside a dimension before clicking the link
In this case you’re probably logged in on rubysoccer.com while the links refer to www.rubysoccer.com
2) you are logged in but is not inside any dimension
In this case you are directed to the enter dimension page
3) you are not logged in
In this case you are directed to the login page
For scenarios 2 and 3 what we could do is store the link you originally wanted to go to and as soon as you enter a dimension take you to that page. For scenario 2 we could try to make you automatically enter the right dimension and take you to the page. Not as simple as it seems.

1) no
2) no
3) no

I just open mail and click match result. And then I can click team name or result and will get to the login page. I don’t get logged out because I can click “back” and continue browsing inside the game.

hehe, yes ! the difference is www. and no www. weird !
