I edited on Wikitravel off-and-on for several years. After a few anonymous edits here, I decided to make an account and contribute more actively. I did that for several years, then took an extended break. I teach English at a university in Japan, and found it was quite easy to create a Simple English Wikipedia page if I am already grading/adapting English Wikipedia content for use with students.
I used an alternate account User:ELTted for editing with students and presenting SEWP to language teachers. I never voted or commented from that other account. It was strictly for editing articles that my students or workshop participants were working on.
