Hey there, I'm Tenryuu. I am primarily a copyeditor and am part of the Guild of Copy Editors (GOCE) project here on Wikipedia. If you need an article proofread, either hit me up on my talk page[a] or send a request over to the Guild. I am also a host over at the Teahouse, so if you have any questions to ask about Wikipedia, experienced editors will answer them for you in a timely manner.
My copyediting process with requests
My process for copyediting articles when requested goes like this:
I accept a request, either from the GOCE's requests page or on my talk page.
I place a {{GOCEinuse}} or {{In use}} template on the top before I start editing.
I complete a preliminary edit (invisible comments added are for my use; please don't delete them) and will ask the requester to reply to any questions I may have on the article's talk page. Please ping me when a reply is given.
Once a day has passed I give the article a second copyedit, whether or not my questions have been answered. If the requester has not responded, I will allow an arbitrary amount of time (typically another 18-24 hours) before making any last-minute edits and marking it as complete.
A third copy edit is made. If the article meets all parties' satisfaction, I will mark the request as complete.
The process may be shortened if there is a backlog drive or blitz going on. If more-than-anticipated copy editing is required, the process will be lengthened.
