Can not Edit notation page on the Website

[Pashkuli Keyboard]

I am aware there has been a recent update to WordPress version on the musicnotationproject.org's Wiki and Website, but I could not see any Login\Edit menus available to make changes to the notation I submitted a few years ago, namely the

Plain Music Notation

Do I need to install this WordPress software to be able to edit the page?

I can remember being able to edit straight from the Browser before, though changes might have happened.

Best regards!

P.S. 

Yes, I am aware my proposal for music notation does not comply to the criteria, yet am grateful to the admins for letting it pass on the website!

Dear, Paul Morris
Can I get access to my page as mentioned in the previous post, regarding the ability to edit its (the page) content, please?

I really need to change some mistakes and amend an important change.

Best wishes!
