I wouldn't have worried too much on this occasion - I was thinking more of future posts.
It occurs to me that tag names (is that what they're called) were probably not what the museum or Archives had in mind, and like some of the other older members of the GMB I use my own name - personally I can never understand why adults should see the need for anything other than their real name.
However, m is your chosen Board moniker, and I don't foresee a problem with using that in the watermark, alghough you might wish to indicate the year................no need to shange these though
