I'm a relative newbie too, having been transcribing/reviewing just since December (and not having much time to devote here of late).
Looking at your link, seems to me you have the formatting down, and unless you plan to go back to it, you can just Submit for Review, same with the Lincoln letter.
They've added a feature that allows you to reopen a submitted transcription, so you can always go back and fill in stuff you couldn't decipher on the first round, as long as it hasn't been opened for review by someone else (and sometimes this can be a long while).
It's an awesome project, and deciphering is such a treasure hunt! Welcome and have fun.
Hi Suzanne! Thanks for taking the time to look over my amateur attempt and sharing your thoughts (and for the warm welcome). I definitely have lots of enthusiasm for this project and hope to help make a dent. - Jill
I have read dozens of journals from the 1850s and am available to help with your transcription.
Hello and welcome to the By the People project!
I too took a look at the page you have linked, and you are entirely right to submit for review! If you do hit a roadblock, and cannot finish a page entirely feel free to save that page. Another person will be able to pick up where you left off.
If you cannot decipher text and there are a few [?] unknowns within your transcription, go ahead and submit for review.
If you have any questions, you may also contact a Community Manager with the project at email@example.com and we'll get back to you shortly.
