Hi,
Well, it certainly seems to be pointing to MySQL.com alright.
Although the domain name registrant is still NuSphere and DNS still appears

Hi Dennis,
There's several ways you can move the datafile location:
1. create a symlink at /var/lib/mysql that points to your data directory
2. you can change or add the 'datadir' variable in your my.cnf file (usually
/etc/my.cnf) see: http://www.mysql.com/doc/C/o/Configuring_MySQL.html

Innobase allows you to specify multiple data files and will use them
automatically. So to keep under the 2gb limit just keep adding 2gb files as
needed. You can see how much space is left in the innobase data files by
doing the following query: show table status from 'dbname' like
'tablename'.
