I suggest to read How to use SCN search . I even prefer it over google. The start could be improved, but if you do not close the session, then each search performs really quick. And there is no need at all to start with a search at a certain space, you can just filter the results by space, this is less typing and you even get aware that there might be solution in other spaces
if you would use a private mail address instead of an S-user to log into SCN, then there is no need to change the user with each client.
I have not seen an increase on questions in another forums (except language specific forums ) . if I ignore the questions which are posted redundant in several sites , then I would even say the other forum(s) are just dead.
