How can I change my username on Google Help Forums?

When you attempt to create an account on Google Help Forums, it asks for a username to use. Each username is unique.

I have an old account which I set up to use my desired username. Now when I try to use my new email account to create a Google Help account, I can’t use that username since my old account is already using it.

How can I remove or change the username from the old account?

ive tried EVERYTHING i can find in forums “VLC is unable to open the MRL ‘dvd:///dev/sr0’ ” nothing works

my lshw

*-cdrom description: DVD-RAM writer product: CDDVDW TS-L633N vendor: hp physical id: 0.0.0 bus info: scsi@1:0.0.0 logical name: /dev/cdrom logical name: /dev/cdrw logical name: /dev/dvd logical name: /dev/dvdrw logical name: /dev/sr0 version: 0300 capabilities: removable audio cd-r cd-rw dvd dvd-r dvd-ram configuration: ansiversion=5 status=nodisc

vlc output

Playback failure: DVDRead could not open the disc “/dev/sr0”. Your input can’t be opened: VLC is unable to open the MRL ‘dvd:///dev/sr0’. Check the log for details.

i dont know what to do. ive only got it to read an audio cd so far.

Please give me dofollow forums list – gaming niche

I know I know forum backlinks aren't highest quality backlinks out there but I still need forums for backlinks.
Please reply or pm me high quality sites which provides DOFOLLOW backlinks in posts or signature, your help is appreciated :)
P.S. it's not necessary it to be forum for webmasters, gaming related forums are preferred.
