Someone has mailed me privately asking this question, so I thought I;d answer here in case it applies to anyone else.
Yes, even if you've not officically volunteered to test you are most welcome to create a Certificate to summarise some testing you may have done yourself.
The only caveat being that I only want test Certificates for the 4.6 cut-off.
It only takes about 2 minutes to Certify a package, and multiple certifications are a boon. So please do (not on the current demo installation, we'll be a day or so getting the live one ready)
