If you would like to submit a bigram to the website then you’ll need a login. You could consider asking me for an ID. But I won’t give you one. I like to manage the entries myself.
It’s not a wiki after all. The website is a diary of sorts; semi biographical in nature and supposedly random.
I use the Submit Bigram page to do all the hard work of publishing an SB picture, categorise it and to give it a few words.
