Hello Michael,

Sorry for bothering you about this but it may be important. In comment #10
of this bug https://bugs.launchpad.net/simple-scan/+bug/550856 the user
posted my e-mail in association with my name, which may cause spam bots to
find it easily. Would you, or some of the other administrators, be able to
delete my e-mail from that post?

Thank you,
ALi
