How do I post an active excel spreadsheet link that i can update throughout the whole 2018 year?

Post #2 in this thread.... www.forabodiesonly.com/mopar/threads/2018-small-block-race-join-the-fun.399661/
I need to update the entries/standings or any other changes as the year goes on. Problem is, I can't post a link to the spreadsheet like i did last year. Last year, i just updated the spreadsheet and the changes automatically showed in the link i posted. This year, I have to turn the spreadsheet into a PDF to post, but then i can't make changes to it. I have to change the spreadsheet, then make another PDF, edit the post and delete the old PDF and upload the new PDF.
However, after a couple of weeks, the edit option goes away so I won't be able to even upload a new PDF.?.?. I wanted to keep the information in the first two post for easy access. i didn't want folks to have to scroll through pages to find the "latest and greatest".

Last, I'm not a computer wizard, so any help I'd appreciate.

Thanks,
