Ok awesome. I went ahead and committed my changes. I hope I did it correctly. I made some fairly substantial changes to wording in some places, so review and criticism are welcome!

phantastic caleb23, please also join https://teamgridcoin.signup.team/ you will receive an email that your application failed due to error, but in fact you will be able to login. Then please come to channel #whitepaper. Then a note about your change in the abstract, the style is perfect, but please also read the chapter "Gridcoin Funded Science", this is about giving Gridcoins to individual projects and is not related to Proof of research directly....

Ah ok, I didn't read that chapter yet! If you have corresponding changes in mind for the abstract, go ahead and put those in. Otherwise, I'll look at it too.
N.b. I don't want to be presumptuous in submitting my changes. I want people to feel free to reject anything I suggest. I hope at least the style and wording can be adopted in some places to improve readability.

hmm.. didn't get an e-mail. I got an error message on https://teamgridcoin.signup.team/. Any idea what might have gone wrong?

ciao @caleb23 i told you wrong: the website gives you an error message, but you should receive an email with instructions to login into http://teamgridcoin.slack.com So, please check again your email. Thanks!

Still no luck! I even tried a different e-mail and checked the spam folders.

Hmmm.. has anyone else reported issues? I suppose someone could try with a dummy e-mail address to see if the problem is with me, not the site. But anyways, I don't want to cause you too much trouble! Maybe you can just let me know if there's something else I could do to debug.

I got first a "certificate error". i added the security exception for the certificate. then i was able to submit another email and received this error message "Something went wrong and we're not quite sure what. We'll look into it as soon as possible!" however i did not receive any email. i tried to reset password for the new account, but did not receive any email. i will check with the teamgridcoin administrator then and come back to you...

I got the certificate error too. And hm ok, I was going to say sorry for the trouble, but if it's not working for anyone at all then it'll have to get fixed one way or the other! Thanks for looking into it though!
