A piece of advice that comes from a Wikipedia editor through several years: Longer texts, posts, articles etc. to be submitted online, are first written in the Notepad program on your own machine. Then copy & paste it to the "edit field" on the site and submit it. If it fails, try again later (look up a fun 2-min. video on Youtube in the meantime) to see if it actually got submitted or not, and if not, copy/paste and submit it again. This avoids both loosing your text, and "embarassing" double posts...
