User activation in multisite should happen in the main blog..
|Reported by:||rahal.aboulfeth||Owned by:|
In multisite mode ( subdomain ) , when a user activates his account, it should happen in the main blog ( or not ? ) .
In ms-settings.php ( line 118 ) , we assume that the main blog is always blog=1 ( which may be wrong ) .
The attached patch uses the constant BLOG_ID_CURRENT_SITE if defined instead.
